| Abstract(in English) | We have developed a Mach-Zehnder interferometric all-optical switch employing intersubband transition in an InGaAs/AlAs/AlAsSb-coupled double quantum well waveguide. The recently discovered cross-phase modulation phenomenon was utilized as the switching mechanism; the nonlinear index of refraction for transverse electric (TE) polarized light is induced by intersubband optical excitation using transverse magnetic (TM) pump light. We demonstrate the demultiplexing operation of 160-Gb/s data signals to 10-Gb/s using this switch. At the input control pulse energy of 8pJ, the demultiplexed signals showed an extinction ratio better than 10dB, and an error-free demultiplexing was achieved. |
