40-Gb/s (4ch X 10-Gb/s) Operation of 1.3-µm Lens-Integrated Surface-Emitting Laser (LISEL) Array Up to 95°C

40-Gb/s (4-ch x 10-Gb/s) operation of a 1.3-µm lens-integrated surface-emitting laser diode array was demonstrated by a CMOS shunt driver. Clearly opened eyes at 10-Gb/s were obtained for 4 channel simultaneous operation at 95°C.
