Abstract
A photonics integrated circuit (PIC) chip includes: an input unit, including at least one optical input (IN) and a number of optical outputs (ISO); a modulation unit (MU) including a number of light modulators (M) having optical inputs(S) coupled to cal outputs ISO of the input unit, and optical outputs (T); a first stage optical switch unit (1SOSU) including a number of optical inputs (I) optically coupled to optical outputs T of the MU, and optical outputs (P), a first subset of which define a first subset of optical outputs (O) of the PIC chip; and a second stage optical switch unit (2SOSU) including a number of optical inputs I and optical outputs (O) that define second subset of the optical outputs O of the PIC chip. Each optical switch of 1SOSU and 2SOSU may be configured in a coupler mode; a bar mode; and/or a cross mode.
