Abstract: The disclosure addresses the problem of increased optical insertion losses in integrated optical switches. It enables the implementation of an array of optical amplifiers, typically with low/moderate gain, to compensate for optical insertion losses in the integrated switches. The amplifier is based on a doped optical fiber which is optically pumped by a pump laser. The integrated optical switch includes a transposer that facilitates connectivity between a set of fibers and a photonic chip through an optical mode conversion. An all passive circuitry is built in a doped fiber amplifier, WDM couplers combine/separate the signals from the pump, and splitters allow sharing of a single pump by multiple amplifiers. In addition, switch pigtails are implemented with the doped fiber.

Abstract: Embodiments are disclosed for providing a serializer and/or a deserializer with redundancy using optical modulators. An example system includes an MZM structure that comprises a first waveguide interferometer arm structure and a second waveguide interferometer arm structure. The first waveguide interferometer arm structure comprises a first segmented electrode associated with at least a first electrode and a second electrode. The second waveguide interferometer arm structure comprises a second segmented electrode associated with at least a third electrode and a fourth electrode. The MZM structure is configured to convert an optical input signal into an optical output signal through application of a digital data signal to the first electrode and the third electrode, and application of a redundant digital data signal to the second electrode and the fourth electrode.

Abstract: An optoelectronic transmitter (10) includes an electro-optic modulator (12), digital driving circuitry (14), and feedback circuitry (30). The electro-optic modulator is configured to modulate an optical signal in response to an electrical drive signal. The digital driving circuitry is coupled to the electro-optical modulator and is configured to generate the electrical drive signal. The feedback circuitry is configured to measure a quantity indicative of a power level of the modulated optical signal produced by the electro-optic modulator, and to adapt a supply voltage to the digital driving circuitry in response to the measured quantity.
