Abstract

An integrated 2 x 2 multimode interference switching device was fabricated with InAs/In_0.15Ga_0.85As quantum dots as the active medium. The device, when probed with a 1.31 μm wavelength laser beam, showed similar responses for TE and TM polarization with initial power splitting ratios of 1:29 (TE) and 1:52 (TM) that were continuously adjustable to 49:1 (TE) and 38:1 (TM) when a change in current of 24 mA was applied through one of the electrodes. This is equivalent to achieving channel-to-channel crosstalk values of better than -15 dB for both polarizations. A 50:50 split ratio was reached at a current of 17 mA. We also present the preliminary results from an integrated variable power splitter that is based on a half-length multimode interference structure.
