摘要： Optical apparatus for combining and splitting optical signals using folded waveguides and method for making the same are disclosed. According to one aspect of the present invention, at least one waveguide used in the optical apparatus is folded around according to a predefined curve to couple to other waveguides. The predefined curve is so designed as to minimize possible insertion loss as a result of such folding of the waveguide. The proper folding of the waveguide leads to modified designs of the optical devices with all the ports on one side so as to simplify the alignment procedures afterward. In addition, the optical device according to the present invention has much smaller footprint and makes it possible to increase higher yield from fabricating substrate material on which the waveguides are formed.

摘要： Techniques for designing optical devices that can be manufactured in volume are disclosed. In an exemplary an optical assembly, to ensure that all collimators are on one side to facilitate efficient packaging, all collimators are positioned on both sides of a substrate. Thus one or more beam folding components are used to fold a light beam up and down through the collimators on top of the substrate and bottom of the substrate.

摘要： Techniques for designing optical devices with passive components for erbium and other doped fiber amplifiers are disclosed. In one aspect, all passive components needed to construct optical amplifiers of both single and multiple-stage forward or backward pumps are integrated without extensively using optical fiber splicing joints. One of the features is to use free-space optics for inter-function cascades among various necessary functions, such as one or more tap couplings, WDM filtering to multiplex (Mux) or de-multiplex (Demux) pump and signal lights, gain-flattening, pump isolation and even performing Mux and Demux of different polarizations.
