抜粋

We proposed and investigated a Michelson interferometer-type wavelength converter with a multimode interference coupler (MIWC-MMIC) as one of the key devices in future DWDM photonic switching networks. The MIWC-MMIC is compact and efficient due to its Michelson interferometer-like structure, which uses an MMIC simultaneously as input and output-side couplers. The dependence of the output characteristics on structural parameters, such as the power-division ratio of the MMIC and the reflection coefficient at semiconductor optical amplifier (SOA) ends, was analyzed to optimize the structure for operation with a low excess loss and a low signal light power. The device was actually fabricated and its preliminary static characteristics were measured. The cross modulation of the converted light by 9.0 dB was attained by introducing a signal light with a power of about -5 dBm.
