Abstract

We demonstrate the fabrication of a 2×2 crosspoint switch monolithically fabricated on the passive active resonant coupler (PARC) platform by utilizing vertical resonant coupling over a taper between an active and a passive waveguide. The coupling taper was 100 μm long with less than 0.15 dB coupling loss. By pushing the mode up and down as and when required, we are able to integrate passive waveguides and electroabsorption modulators on one chip. The static performance of the switch has been tested, and a modulation depth of 30 dB has been achieved at the wavelength of 1.57 μm for an applied bias of 2.5 V.
