摘要

Modern systems often provide complex functionality that can be realized by tailoring together elements of simpler functionality. Multiplicity of simple optical functions (response shapes), when densely fabricated on a chip, can promote the concept of a field-programmable optical array. Shaping of the frequency response, or otherwise an electrical-to-optical response, is studied and demonstrated by means of a racetrack-shaped ring resonator designed and fabricated in the so-called double injection configuration. This configuration possesses a unique property that allows two free spectral range states (regular, 2 x regular) to exist for a single ring length. Shaping is realized by properly selecting different coupling coefficients that provide a variety of interesting responses. Here, we demonstrate various shapes including: sinusoidal, triangular (linear), square (bandpass), dips and peaks (two states), spikes (tangent-like), interleaver and a so-called 20dB-min parameters-insensitive-response modulator. The transmission responses were experimentally realized, fabricated in a silicon-on-insulator platform and characterized at wavelengths around 1,550 nm.
