摘要： In one embodiment, a silicon photonic integrated circuit (PIC) includes a pair of Mach-Zehnder Interferometers (MZI) with a phase shifter to function as a 1x2 optical switches. On one path between the MZIs is a wavelength interleaver. The MZI switch can be controlled to either an all-pass mode or a by-pass mode, therefore setting configurable optical demultiplexing bandwidths to support dual 1.6 T FR8/800G FR4 network backward compatibility. The configurable multiplexer operates at set-and-forget mode for the entire operating temperature and the product’s lifetime.

摘要： A multiplexing AWG device capable of producing an ultra-wideband, low ripple, flat-top signal is presented. The AWG device includes an AWG unit and a two-section waveguide coupled to the AWG unit. The two-section waveguide has a first section and a second section. The first section produces a signal having a double-peak field profile and has a first input end and a first output end. The second section reduces the phase variation of the signal having the double-peak field profile exiting the first section. The second section has a second input end that is coupled to the first output end. For example, the first section may be a parabolic tapered waveguide and the second section may be a rectangular waveguide.

摘要： The optical component includes an array waveguide grating having a plurality of array waveguides. The optical component also includes a light distribution component configured to receive a light signal through an inlet port and distribute the light signal to a plurality of the array waveguides. The optical component further includes an output light distribution component configured to receive the light signal distributed to the array waveguides. The light distribution component is configured such that a light signal received through the inlet port with a non-periodic intensity distribution is received in the output light distribution component with a periodic intensity distribution. The period intensity distribution can have a shape that approximates a sinc function.

摘要： A method of making a planar lightwave circuit (PLC) waveguide capable of being integrated with a surface-mounted component is presented. The method entails etching a silicon substrate to form a slanted wall, forming a nonreflective waveguide portion on the silicon substrate, and depositing a reflective layer on the slanted wall. Light travels through the nonreflective waveguide portion in substantially a first direction, and the light from the nonreflective waveguide portion strikes the reflective layer to be redirected in a second direction. The second direction may be the direction toward the surface-mounted component. A PLC waveguide device made with the above method is also presented.

The ridge includes a waveguide region configured to propagate light signals and a flange region extending across a longitudinal axis of the waveguide region. The method also includes removing at least a portion of the flange region so as to expose a facet aligned with the waveguide region such that light signals propagated along the waveguide region are transmitted through the facet.

摘要： A unique sensor is used to detect a transmission impairment that may have affected incoming optical channel signals. The sensor, more specifically, selects a group of the incoming channel signals and generates a first power signal, P0, over the selected group of signals and generates a second power signals, P1, over a weighted version of the selected group of channel signals. The sensor then generates, as a function of the first and second power signals, P0 and P1, a signal indicative of whether the particular transmission impairment affected the levels of individual ones of the incoming channel signals. If so, then control apparatus offsets the impairment accordingly.
