Paper Abstract

We propose a silicon modulator in a multi-mode waveguide based on the anti-symmetric Bragg grating (AS-BG). When the incident light is in the fundamental transverse electric (TE0) mode, the reflected light of the AS-BG is in the first order transverse electric (TE1) mode, rather than the TE0 mode. Therefore, the reflected TE0 mode is radiated in a tapered waveguide (WG) that connects a multi-mode and single-mode WG. As a result, the back reflection of the Bragg grating (BG) based silicon modulator avoids the utilization of an optical circulator, especially when ingrating with a semiconductor laser, which is susceptible to the external light.
