摘要:
Optical networks can comprise a branch structure with the de-multiplexing/multiplexing structure that operates to disperse a plurality of optical bands. Thus, the optical network comprises an optical network connection with a common optical channel, a plurality of de-multiplexed branch optical service connections and the de-multiplexing/multiplexing structure. In some embodiments, one optical band can be used to deliver input from a common channel to the branch node and the other optical band can carry output along the common channel from the branch node. The de-multiplexing/multiplexing element can be an arrayed waveguide grating. The AWG can have desirable architecture to efficiently provide the corresponding functions with respect to the two optical bands. Appropriate photodetectors and light sources can be associated with the AWG.

Methods of using an optical device capable of distributing the optical power presented at an input to specified ratios in two output ports. The devices and methods described herein have the ability to broaden the range of wavelengths over which the splitting ratio is even, or substantially even. Methods involve achieving a desired splitting ratio over a broad or ultra-broad wavelength range.
摘要:
Optical integrated circuits are disclosed having a gap traversing the lens or the waveguide grating and an actuator that controllably positions the optical integrated circuit on each side of the gap. As a result, the thermal sensitivity of the optical integrated circuits, for example, arrayed waveguide gratings, is mitigated. Also disclosed are methods for fabricating optical integrated circuits employing the gap and actuator.

摘要:
The invention provides integrated optical matching elements for use in integrated optical devices. The matching elements each comprise one or more lenses. The lenses may have low index contrast with the surrounding medium. Required dioptric power is achieved by using a train of lenses. Optical matching elements according to the invention can be used to enhance the optical coupling between channel waveguides and slab waveguides. The insertion loss of devices such as optical power splitters, optical couplers and arrayed waveguide grating routers can be reduced by incorporating optical matching elements according to the invention.
