    Abstract: An optical assembly includes a light source for providing a beam of light, a lens system configured to expand and collimate the beam of light, and a configurable beam injector, wherein the beam injector contains a first grid plate and a second grid plate to block individual beams of light. The first grid plate and the second grid plate may be configured such that each grid plate respectively corresponds to particular MEMS mirrors. The grid plates can be configured to have pathways that allow for beams of light to be passed through and other pathways which are blocked to prevent the passage of light. The first grid plate and second grid plate may thus block or allow for transmission of beams of lights to those particular MEMS mirrors. The second grid plate can be configured to be easily swappable during or removable to allow for a different set of beams of light, corresponding to a different set of MEMS mirrors, to be blocked. The second grid plate can be configured to be rotated or slid linearly within a housing.

    Abstract: The present disclosure provides systems and methods for preventing or minimizing optical crosstalk in an optical circuit switch (“OCS”). The OCS may include a collimator lens assembly. The collimator lens assembly may include a lens array defined by a plurality of ports. Each port may include a lenslet and a spacer paired with each lenslet. Crosstalk may occur when light from other ports enter the target port's optical fiber. The collimator lens assembly may include an insert positioned relative to the lenslet. The insert may define an aperture that allows light from the target port to pass through. The insert may prevent a portion of light from adjacent ports from passing through the aperture. The insert may be located between the lenslet and spacer, on the curved surface of the lenslet, or on a plate located at a distance from the front of the lenslet.

    Abstract: An apparatus including a photonic integrated circuit (PIC) coupled to an optical bench is disclosed. The PIC includes at least one grating coupler disposed thereon and the optical bench includes an optical system disposed thereon. The apparatus also includes an integrated heater at an upper surface of the PIC under the optical bench or at a bottom surface of the optical bench over the PIC. The apparatus also includes a layer of solder disposed between the PIC and the optical bench for coupling the bottom surface of the optical bench to the PIC. In some implementations, the layer of solder is in thermal communication with the integrated heater.

    Abstract: An optical links diagnostic system (LDS) and its operation within an optical circuit switch (OCS) for measurement and diagnosis of fiber-optic network fiber performance and quality is disclosed. The LDS can contain two photodetectors, a laser source, and be coupled to an OCS. Optical circulators can further be linked to the OCS. The LDS can be used both as an optical time domain reflectometer (OTDR) or as an optical return loss (ORL) meter and can automate the diagnosis of the fiber optical network fiber insertion loss and return loss.
