Compact GaAs/AlGaAs Waveguide Optical Switch with Adjustable Y-Junction

Not Accessible

Your library or personal account may give you access

Abstract

A compact GaAs/AlGaAs optical switch with a y-junction structure in which the two output arms can be individually turned on or turned off electrically is demonstrated here for the first time. This initial experimental result shows that switching operation has been achieved with a crosstalk of less than -12 dB for a device with a transition length of less than 400 μm at 1.06-μm wavelength.
