    摘要： A polarization insensitive optical phased array is provided, for LIDAR or other purposes. A polarization rotator splitter or two-dimensional grating coupler provides two components of co-polarized (e.g. TE-polarized) light. Each component can be routed to a separate optical phased array (OPA) component, and light output of one of the OPA components is rotated in polarization by use of a half wave plate. A polarization controller can receive and control the two components of co-polarized light and then passes the controlled light to the two OPA components. A single OPA component can also be used along with a controller which combines the two components of co-polarized light into a single output, passed to the single OPA component.

    摘要： An optical coupler at an edge of a photonic integrated circuit (PIC) is provided and configured to match a mode of a waveguide of the PIC to a mode of an external optical fiber. A core of the waveguide terminates prior to the edge and can include an inverted taper for mode enlargement. The waveguide cladding includes an inverted taper and is surrounded by an outer cladding material of lower refractive index, forming a second waveguide. The cladding and outer cladding cooperate to guide light between the core and the edge while the inverted taper contributes to mode enlargement. The outer cladding material is selected to have a refractive index which facilitates the mode matching to optical fiber. The coupler can be provided using lithography. Material underneath the waveguide cladding can be removed by an undercutting process and the outer cladding material deposited in place thereof.

    摘要： A monitoring and calibration apparatus for an optical networking device such as ROADM is provided. Reflectors are integrated into the device, for example at the ends of optical interconnect cables. The reflectors reflect light in specific monitoring wavelengths and pass other wavelengths such as those used for communication. A light source emits monitoring light which is reflected by the reflector and measured by a detector to measure the integrity of optical paths. The optical paths can include optical cables and cable connectors. Path integrity between different modules of the device can therefore be monitored. Multiple reflectors, reflecting light in different wavelengths, can be placed in series along the same optical path and used to monitor multiple segments of the path. A wavelength selective switch (WSS) of the device can be used to route monitoring light to different optical paths. The WSS also operates to route communication signals in the device.
