Abstract: Disclosed are a testing unit, system, and method for testing and predicting failure of optical receivers. The testing unit and system are configured to apply different values of current, voltage, heat stress, and illumination load on the optical receivers during testing. The test methods are designed to check dark current, photo current, forward voltage, and drift over time of these parameters.

Abstract: Optical components and associated methods of manufacturing are provided. An example optical component includes a body defined by an optical interposer substrate and a passivation layer applied to the optical interposer substrate. The optical interposer substrate defines a first surface of the body, and the passivation layer defines a second surface of the body opposite the first surface. The passivation layer includes a metallic shielding element configured to prevent interference between the first surface and the second surface. The optical component further includes an opening extending from the second surface to the optical interposer substrate, the opening defining an optical path through the passivation layer. The optical interposer substrate receives an optical signal from an optical transmitter supported by the second surface via the optical path.

Abstract: Various embodiments provide a method for fabricating a couplable electro-optical device. In an example embodiment, the method includes fabricating at least one raw electro-optical device on a substrate; applying lens material to a working stamp; aligning the substrate and the working stamp; pressing the substrate onto the lens material until the distance between the substrate and the working stamp is a predetermined distance; and curing the lens material to form an integrated lens secured to the at least one electro-optical device on the substrate. An anti-reflective coating layer may be optionally applied on top of the molded lens. The couplable electro-optical device may be incorporated into a receiver, transmitter, and/or transceiver using passive alignment to align the couplable electro-optical device to an optical fiber.
