Abstract: There is provided a reconfigurable optical modulator comprising a light source and a splitter operative to receive an input signal from the light source and to split the input signal into a plurality of split signals. The optical modulator comprises a plurality of optical amplifiers, each being operative to receive one of the plurality of split signals as an input and to act as a switch having a first state where the split signal is blocked and a second state where the split signal is amplified. The optical modulator comprises a plurality of modulators, each being operative to receive an amplified split signal from one of the plurality of optical amplifiers and to modulate the amplified split signal into a modulated signal. The optical modulator comprises an optical combiner operative to combine a plurality of modulated signals produced by the plurality of modulators to thereby produce a modulated output signal.

Abstract: Systems and methods according to these exemplary embodiments provide for optical interconnection using optical splitters and interferometer-based optical switching. Optical signals can be routed from an input port to one or more output ports via at least one splitter and at least one interferometer, e.g., a Mach Zehnder interferometer. According to one exemplary embodiment, signal degradation associated with signal splitting is mitigated by using a binary tree of splitters and interferometers between input ports and output ports.

Abstract: A backplane for a computing system may include a connector configured to provide a detachable mechanical coupling with a circuit board, and an optical signal path configured to carry optical signals. In addition, an optical bypass switch may be configured to couple optical signals from the optical signal path to the circuit board and to couple optical signals from the circuit board to the optical signal path responsive to an enabling signal. The optical bypass switch may be further configured to transmit optical signals therethrough to bypass the circuit board responsive to an absence of the enabling signal. Related circuit boards, computing systems, bypass switches, and methods are also discussed.

Abstract: The disclosure relates to a transceiver operative to transmit and receive optical signals. The transceiver comprises a laser, a power splitter, a dual-polarization in-phase and quadrature modulator, DP-IQM, a first circulator (C1, C3), a second circulator (C2, C4), a first optical polarization controller, PC, a second optical polarization controller and a dual-polarization coherent receiver, DP-CRx. There is provided a system comprising a first transceiver and a second transceiver as described previously. The transceiver requires neither high speed DSP nor high resolution data converters to achieve 50 Gbaud DP-16 QAM, DP standing for dual polarization and QAM standing for quadrature amplitude modulation, yielding 400 Gb/s over 10 km below the 2.2×10−4 KP4 forward error correction (FEC) threshold.

Abstract: Optical waveguide coupling ratios can be modified for a package by providing a substrate with a photonic circuit disposed on a first section of the substrate and a plurality of optical waveguides formed in glass disposed on a second section of the substrate, the waveguides being connected to the photonic circuit, adjacent ones of the waveguides having a fixed coupling ratio. A three-dimensional region of the glass abutting an end of one or more of the waveguides is lased to change a refractive index of the glass in each three-dimensional region, and thereby extend a length of each waveguide abutting one of the three-dimensional regions so that the coupling ratio between that waveguide and an adjacent waveguide is changed as a function of the extended length. The lasing is controlled based on feedback so that each coupling ratio changed by the lasing varies by less than a target amount.
