Embodiment Construction

[0018] As used herein, the terms "circuits" and "circuitry" refer to physical electronic components (i.e., hardware) and any software and / or firmware ("code") that configures the hardware, Executed by or otherwise associated with hardware. As used herein, for example, a particular processor and memory may include a first "circuitry" when executing a first one or more lines of code and a second "circuitry" when executing a second one or more lines of code. "Circuit". As used herein, "and / or" refers to any one or more items in the list connected by "and / or". For example, "x and / or y" means any element in the three-element set {(x),(y),(x,y)}. In other words, "x and / or y" means "either or both of x and y". As another example, "x, y, and / or z" represents the seven-element set {(x), (y), (z), (x, y), (x, z), (y, z), ( Any element in x,y,z)}. In other words, "x, y and / or z" means "one or more of x, y and z". As used herein, the term "exemplary" means serving as a non-limiting ...

Abstract

Methods and systems for a free space CWDM MUX / DEMUX for integration with a grating coupler based silicon platform may include an optical assembly comprising a lens array and a plurality of thin film filter splitters having angled reflective surfaces. The optical assembly may be operable to receive an input optical signal comprising a plurality of optical signals at different wavelengths via an optical fiber, focus the input optical signal onto a first thin film filter splitter, reflect a first of the optical signals into the lens array and passing others to a second thin film filter splitter,and reflect a second optical signal into the lens array and passing others to a third of the plurality of thin film filter splitters.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit to U.S. Provisional Application No. 62 / 543,679, filed August 10, 2017, and U.S. Provisional Application No. 62 / 545,652, filed August 15, 2017, both of which are incorporated herein by reference in their entirety . technical field [0003] Aspects of the disclosure relate to electronic assemblies. More specifically, certain implementations of the present disclosure relate to methods and systems for a free-space coarse wavelength division multiplexing (CWDM) multiplexer / demultiplexer (MUX / DEMUX) integrated with a grating coupler-based silicon platform . Background technique [0004] Traditional methods for CWDM multiplexing and demultiplexing can be expensive, cumbersome and / or inefficient, for example, they can be complex and / or time-consuming, and / or can have limited response due to loss Spend. [0005] Further limitations and disadvantages of conventional and traditiona...
