ABSTRACT We demonstrate a very high quality (Q) factor wavelength filter based on a buried heterostructure (BH) microresonator platform technology. A 200-μm-radius BH ring resonator is integrated with a semiconductor optical amplifier (SOA) using offset quantum wells for loss-cancellation. The resonator is operated near critical coupling at ISOA=29 mA, which yields a coupling-limited Q of 2.0×105 with an extinction of -26 dB at the resonant wavelength.
