Optical Detection of Lead Ion with Surface Plasmon Resonance Configurations

Ali Abdulkhaleq Alwahib Yasmin Mustapha Kamil M. H. Abu Bakar Mohd Adzir Mahdi F. H. Suhailin

We review our recent finding on the development of surface plasmon resonance sensors for lead ion detection in aqueous solution. Both Kretschmann and optical fiber configurations were utilized to investigate the angular and spectral responses of plasmonic wave at different concentrations of lead ion.

Microstructured silicon fibre devices

F. H. Suhailin

Silicon photonics is an advanced platform for the development of compact integrated optical devices. Major breakthroughs such as light generation, signal amplification and high-speed modulation have been demonstrated in silicon waveguides due to their large nonlinear effects. Recent fabrication methods have enabled the infiltration of crystalline and amorphous semiconductor materials inside silica capillaries to combine the excellent optoelectronic properties of silicon with the waveguiding capabilities of fibres. This new class of waveguide maintains many of the advantageous properties of commercial silica glass fibres such as robustness and flexibility, as well as offering the potential for seamless integration within existing networks. Furthermore, the silicon fibre platform can also be post-processed to fabricate novel micron-scale devices, beyond what is achievable in their planar counterparts. In this thesis, two forms of fibre-based semiconductor devices have been investigated; tapered silicon core waveguides and whispering gallery mode microresonators. These devices were fabricated as a unique approach to enhance the light-matter interactions for the development of all-optical signal processing devices. Improvements in the crystallinity and the optical transmission properties of polysilicon core fibres were achieved via fibre tapering, enabling the first demonstration of nonlinear propagation in this material. Moreover, different forms of resonators were fabricated from amorphous and polycrystalline silicon core fibres. Ultrafast all-optical modulation via the Kerr nonlinearity is demonstrated at picoseconds switching speeds using pure amorphous silicon resonators and in hybrid silica glass and polysilicon core resonators.

Kerr nonlinear switching in a hybrid silica-silicon microspherical resonator

Optics Express (2015)

F. H. Suhailin N. Healy Yohann Franz M. Sumetsky John Ballato

A hybrid silicon-core, silica-clad microspherical resonator has been fabricated from the semiconductor core fiber platform. Linear and nonlinear characterization of the resonator properties have shown it to exhibit advantageous properties associated with both materials, with the low loss cladding supporting high quality (Q) factor whispering gallery modes which can be tuned through the nonlinear response of the crystalline core. By exploiting the large wavelength shift associated with the Kerr nonlinearity, we have demonstrated all-optical modulation of a weak probe on the timescale of the femtosecond pump pulse. This novel geometry offers a route to ultra-low loss, high-Q silica-based resonators with enhanced functionality.

Multisoliton generation using an erbium doped fiber amplifier incorporating a fiber optic ring resonator

Jalil Ali F. H. Suhailin P.P. Yupapin S. F. Norizan K. Thambiratnam

We have successfully generated the mutisoliton pulses using a Gaussian pulse in a fiber optic ring resonator incorporating an erbium-doped fiber (EDF) and a semiconductor optical amplifiers (SOAs). The multisoliton memory time within the system is also measured. Initially, the Gaussian input pulse is pumped and amplified through the EDF and the SOAs, respectively. The suitable experimental values, such as drive current, coupling power, and the fiber ring radius, are arranged to generate the multisoliton pulses. In application, the wider multisoliton band can be generated by adjusting the suitable system parameters. Results obtained have shown that the multisoliton with a free spectrum range and spectrum width of 2.4 and 0.96 nm is achieved. The memory time and the maximum soliton output of 15 min and of 5.94 dBm, respectively, are noted.

Tapered polysilicon core fibers for nonlinear photonics

Optics Letters (2016)

F. H. Suhailin Li Shen N. Healy Limin Xiao Maxwell Jones

We propose and demonstrate a novel approach to obtaining small-core polysilicon waveguides from the silicon fiber platform. The fibers were fabricated via a conventional drawing tower method and, subsequently, tapered down to achieve silicon core diameters of ∼1 μm, the smallest optical cores for this class of fiber to date. Characterization of the material properties have shown that the taper process helps to improve the local crystallinity of the silicon core, resulting in a significant reduction in the material loss. By exploiting the combination of small cores and low losses, these tapered fibers have enabled the first observation of nonlinear transmission within a polycrystalline silicon waveguide of any type. As the fiber drawing method is highly scalable, it opens a route for the development of low-cost and flexible nonlinear silicon photonic systems.

Nonlinear optics in silicon fibre micro structures

Photonics North (2014)

Anna C. Peacock Natasha Vukovic F. H. Suhailin P. Mehta N. Healy

Silicon photonic devices are becoming an increasingly popular platform for nonlinear optical applications owing to the high Kerr nonlinearity and tight optical confinement. Although typically these devices are fabricated from silicon planar wafers using standard photolithographic and etching techniques, more recently alternative fiber-based platforms have emerged [1]. In this paper we will review methods to fabricate novel micro-scale devices from our silicon fiber platform using standard fiber post-processing techniques. Fig. 1 shows two geometries that are unique to the fiber platform; microcylindrical silicon resonators [2] and tapered silicon core waveguides [3]. The ability to arbitrarily tailor the dimensions in these devices to manipulate the light confinement is of particular interest for low power, high speed nonlinear optical processing. For example, we will show that the ultra-small mode volume of the resonators can be exploited for ultrafast Kerr optical switching and modulation, whilst the longitudinally varying waveguide parameters of the tapers can be used for nonlinear pulse shaping at modest power levels.
