Title: Hybrid wavelength converter of transit phase modulation type
Inventor: SATOU RIEKO
IPC: G02F1/365
Filed: 2001-02-14
Abstract: PROBLEM TO BE SOLVED: To shorten the time for manufacturing and to improve the yield. SOLUTION: A hybrid wavelength converter 100 of the transit phase modulation type is constituted, by forming a Mach-Zehnder optical interference circuit 120 on a platform 110 and mounted with one semiconductor optical amplifier array 130, having four SS-SOA elements 131 to 134. The SS-SOA elements 131 and 133 are connected in series by an arm waveguide 123, and since the SS-SOA elements 132 and 134 are connected in series by an arm waveguide 124, the interaction length of a signal light Ps and a control light Pc increases and an extinction rate becomes high, making it possible to lower the signal light power and the control light power.
