Abstract

We propose an optical power stabilized LD module without APC circuit and monitor photodiode (PD) for optical burst-mode communications. It utilizes the temperature dependence of LD wavelength. With the designed filter, the power drop is suppressed to 0 dB at full operating temperature range and the optical signal power level reduction is only 1.2 dB at 15/spl deg/C and 0 dB at 700/spl deg/C in 1.3 μm InGaAsP-InP FP MQW LD. The method is demonstrated by using fiber-coupler-filter, and the modulation characteristics are measured.
