Photonic correlation based on four wave mixing

Refat Kibria

Modern high-performance signal processing applications face constantly increasing processing speeds. The use of photonics potentially offers a much higher bandwidth and faster processing than what can be achieved in the electronic domain. This thesis inve

Nonlinear mixing based photonic correlator

Refat Kibria Lam Anh Bui Michael W. Austin

We propose a novel correlation technique based on matched filtering using four wave mixing (FWM) in a length of highly nonlinear fiber (HNLF). A pump wavelength which is modulated by an input bit stream is mixed with wavelength channels to generate idler wavelengths which also carry the bit stream. The idler wavelengths are differentially delayed and summed at a photodetector to produce the required correlation function. This scheme has been experimentally demonstrated and the measured results verify the proposed concept. The technique allows remoting of the transmitter.

All Optical Signal-Processing Techniques Utilizing Four Wave Mixing

Photonics (2015)

Refat Kibria Michael W. Austin

Four Wave Mixing (FWM) based optical signal-processing techniques are reviewed. The use of FWM in arithmetical operation like subtraction, wavelength conversion and pattern recognition are three key parts discussed in this paper after a brief introduction on FWM and its comparison with other nonlinear mixings. Two different approaches to achieve correlation are discussed, as well as a novel technique to realize all optical subtraction of two optical signals.

Millimeter wave generation based on optical frequency multiplication in radio over fiber systems

Tahmid Aziz Chowdhury Md. Mahfuzul Azam Ghuri Refat Kibria

In this paper an overview of the generation schemes for millimeter wave signals has been reported and a comparative analysis is made to decide their suitability to modern radio over fiber systems. Photonic millimeter-wave (mm-wave) generation using optical frequency multiplication (OFM) is considered as a cost-effective solution in modern radio over fiber (RoF) systems. This paper provides an insight to the advancement of this field in recent times by reviewing the pros and cons of a few of the latest OFM architectures. Simulation of an RoF link based on an optical frequency multiplication technique is performed and results show that the link exhibits satisfactory performance for a range upto 30 km single mode fiber.

HNLF-Based Photonic Pattern Recognition Using Remote Transmitter

IEEE Photonics Technology Letters (2014)

Refat Kibria Lam Anh Bui Arnan Mitchell Michael W. Austin

In this letter, a novel correlation technique based on matched filtering using four wave mixing with possible remote transmission is proposed. A pump wavelength, which is modulated by an input bit pattern is mixed with wavelength channels in a highly nonlinear fiber to generate idler wavelengths, which also carry the bit stream. Specific idler wavelengths are selected using software control of an optical processor to generate the reference template. These idlers are then differentially delayed and summed at a photodetector to produce the required correlation function. This scheme has been experimentally demonstrated and the measured results verify the proposed concept.

H.264/AVC-based multiple description coding for wireless video transmission

Refat Kibria Joohee Kim

Multiple description coding is a promising solution for robust video communication over nonprioritized and unpredictable networks. In this paper, we propose a new multiple description coding scheme for the H.264/AVC video coding standard which enables adaptive and robust video transmission in wireless networks. In the proposed MDC, each description has a different prediction loop and contains additional motion information for the frames included in the other description. This additional motion information is used to enhance the reconstructed video quality when only one of the two descriptions is received. Simulation results show that the proposed MDC has a low redundancy and outperforms single description coding (SDC) for video transmission over unpredictable and error-prone networks.

(IPC) A Photonic Correlation Scheme Using FWM With Phase Management to Achieve Optical Subtraction

IEEE photonics journal (2013)

Refat Kibria Lam Anh Bui Arnan Mitchell Michael W. Austin

In this paper, a photonic correlation scheme that allows accumulation of negative signals is presented. The scheme uses four-wave mixing of pairs of signal and pump wavelengths, which are chosen such that they create idler wavelengths at a common wavelength. The total optical power at this target idler wavelength depends on the relative phase of each pump and signal wavelength. This concept has been applied to form a correlator where signal wavelengths are modulated by an input bit stream and mixed with pump wavelengths representing a reference bit pattern. This approach provides a correlation function with smaller unwanted noise peaks due to cancelation in the subtraction process. Simulation of the proposed correlation technique has been used to verify the concept using both intensity and phase modulation of the signal wavelengths.
