We propose a flexible optical receiver module for an optical access system that offers not only user/service-multiplexing but also rate-extendibility. Proposed module compensates delays of over 9.6 nsec, caused by GVD, and provides physical rate flexibility.

A very low threshold current lasing operation was demonstrated with a composite resonator VCSEL using a concave external mirror. Sub-harmonic active mode-locking produced light output with a repetition rate of 10.56 GHz.

Based on a robust THz gain medium that rapidly depopulates the lower state using resonant LO-phonons and a novel metal-metal waveguide structure for mode confinement, we have developed THz quantum- cascade lasers with many performance records. These include but not limited to: the highest pulsed operating temperature of-170 K, the highest CW operating temperature of 117 K, the longest wavelength of-190 mum, and the highest output power levels of-250 mW. Using these lasers and a 320times240 pixel focal-plane array camera, real-time THz imaging is performed at a rate of 20 frames/second.

We report 4H-SiC p-i-n recessed window avalanche photodiodes with low dark current and high quantum efficiency. For a circular device of 250 mum diameter, the device demonstrated a responsivity of ~135.5 mW/A (external quantum efficiency = ~64%), a dark current ~90 pA (~0.183 mum/cm2) at a photocurrent gain of 1000, and an excess noise factor k of slightly less than 0.1.
