Optical Signal Modulation of Semiconductor Soliton Device with Circular Ring Resonator

Abstract

We demonstrated a novel optical signal modulation by the interaction of spatial solitons generated from a semiconductor ridge waveguide circular ring resonator with an input signal from the Y-junction coupling section. By controlling the optical power of the circular ring resonator with emission at 660 nm, in which a spatial soliton waveguide is formed owing to the photorefractive effect, one can manipulate the transmission of the input signal through the soliton waveguide. For an input signal of 1560 nm, the transmission through this soliton waveguide can be modulated within a 10 dB depth. The fabrication and optical properties of the fabricated devices are presented.
