    摘要: A circuit board has embedded optical fibers terminating in fiber ends which face into holes defined in the circuit board and optoelectronic emitter or detector modules mounted in the holes in optical coupling with the fiber ends. Each module is electrically connected to circuit traces on the circuit board and is optically coupled to one or more optical fibers terminating on a side surface of the hole. The modules have an optical axis oriented into the hole and a reflector supported in the hole for optically coupling the photo emitter/detector module with the fiber ends on the side surface of the hole.

    摘要: A thermo-optic device may be formed with trenches that undercut the substrate beneath the thermo-optic device. Through the removal of the underlying substrate, the heat dissipation of the thermo-optic device may be reduced. This may reduce the thermal budget of the device, reducing the power requirements for operating the device in some embodiments.

    摘要: A method of deploying a passive optical combiner that is a broad bandwidth spectral wavelength combiner for combining the outputs from multiples transmitter photonic integrated circuit (TxPIC) chips and, thereafter, the amplification of the combined channel signals with a booster optical amplifier couple between the passive optical combiner and the fiber transmission link. The booster optical amplifier may be a rear earth fiber amplifier, such as an erbium doped fiber amplifier (EDFA), or one or more semiconductor optical amplifiers (SOAs) on one or more semiconductor chips. Such a combination of optical components simplifies the design of individual TxPICs and other such optical communication PICs, which has to take into consideration the nonlinear effects of difficult, high loss single mode fiber (SMF) links or other fiber-type links by allowing a higher power per channel to be achieved compared to the case where channel amplification is attempted directly on the TxPIC chip through the deployment of on-chip optical amplifiers, such as semiconductor optical amplifiers (SOAs), integrated in locations following the electro-optic (EO) modulators, if not integrated also at other locations on the same chip

    摘要: An optical network may include a detector for detecting the power of each of a plurality of channels of a wavelength division multiplexed optical signal in one embodiment of the present invention. Each channel may be conveyed to an interface underneath a detector by way of a core formed in the substrate. The interface may include a trench with one side surface angled to form a reflector to reflect light upwardly to be detected by the detector. The trench may be filled with a convex microlens.

    摘要: In an embodiment, light from a single mode light source may be deflected into a low index contrast (LIC) waveguide in an opto-electronic integrated circuit (OEIC) (or nullopto-electronic chipnull) by a 45 degree mirror. The mirror may be formed by polishing an edge of the die at a 45 degree angle and coating the polished edge with a metal layer. Light coupled into the LIC waveguide may then be transferred from the LIC waveguide to a high index contrast (HIC) waveguide by evanescent coupling.
