We demonstrate a quantum-well Y-branch switch designed for low crossta
lk, low propagation loss, and compact size. The active waveguide core
is composed of InGaAsP-InP quantum wells for reverse-bias electrorefra
ctive switching. We achieve -20-dB crosstalk and 2-dB/cm propagation l
oss with a 2-mm-long switch.
