| Abstract(in English) | A polarization insensitive electroabsorption modulator (EAM) integrated with a semiconductor optical amplifier (SOA) has been developed with a ridge waveguide structure. Low polarization sensitivities of less than 1dB were successfully achieved by a butt-coupled junction at the interface which can independently optimize strained MQW structures of the EMA and the SOA. A maximum fiber to fiber gain of 4dB was obtained at a SOA injection current of 200 mA with a 15dB extinction ratio at-3V EAM bias. When the input light was inserted from the EAM side, it was confirmed that chirp parameters significantly reduced to approximately 0.4 at 0 V EAM bias. |
