Abstract: A photonic integrated circuit is provided that is adapted to compensate for an unintentional manufactured refractive index profile, such as a gradient, that arises due to manufacturing variance. The photonic integrated circuit including at least a thermal source (325) and a spaced thermal sink (330) to induce a thermal gradient in the photonic integrated circuit between the thermal source (325) and the spaced thermal sink (330), the thermal gradient imparts an opposing thermal refractive index profile to correct for the manufactured refractive index profile. The photonic integrated circuit may be constructed with features that have an intentional structured refractive index profile that ensures any unintentional manufactured refractive index profile is correctable by the opposing thermal refractive index profile induced by the thermal source (325).

Abstract: A method and apparatus is provided for control of plural optical phase shifters (D1, D2) in an optical device, such as a Mach-Zehnder Interferometer switch (120). Drive signal magnitude is set using a level setting input (133) and is used for operating both phase shifters (D1, D2), which may have similar characteristics due to co-location and co-manufacture. A device state control signal (134) selects which of the phase shifters (D1, D2) receives the drive signal. One or more switches may be used to route the drive signal to the selected phase shifter (D1, D2). Separate level control circuits and state control circuits operating at different speeds may be employed. When the phase shifters (D1, D2) are asymmetrically conducting (e.g. carrier injection) phase shifters, a bi-polar drive circuit (110) can be employed. In this case, the phase shifters (D1, D2) can be connected in reverse-parallel, and the drive signal polarity can be switchably reversed in order to drive a selected one of the phase shifters.
