Abstract(in English) | An InGaAs/InAlAs five-layer asymmetric coupled quantum well (FACQW) for giant electrorefractive (ER) sensitivity was proposed and studied theoretically and experimentally. Giant ER sensitivity |dn/dF| (~4.4 x 10^<-4> cm/kV) over 100 nm wavelength range can be expected at around electric field F= -30~-60W/cm. Results of photoabsorption current measurements were consistent with the calculated ones. In addition, a compact and low-voltage FACQW modulator and a 2 x 2 switch with multi-mode interferer (MMI) couplers were also proposed and static operation characteristics were analyzed using beam propagation method (BPM). The switching voltage can be reduced to 0.1~0.2V. |
