Abstract:Semiconductor optical amplifier (SOA) is wildly used as gain media in photonic integrated circuit, as it is integrable with various devices, including wavelength filter, on a same wafer. Quantum dot (QD) has been known to realize high temperature operation without using thermo-cooler, the saturated output power was not high due to the limited density of state in QD. To realize high saturated output power under high temperature, we have exploited active multi-mode interferometer (active-MMI) configuration on QD… Show more
