摘要： Integrated optical component combine the functions of a Variable Optical Attenuator (VOA), a tap coupler, and a photo-detector, reducing the size, cost, and complexity of these functions. In other embodiments, the integrated optical component combines the functions of an optical switch, a tap coupler, and a photo-detector. A rotatable mirror is used to adjust the coupling of light from an input port or ports to one or more output ports. A pin hole with a surrounding reflective surface is used at the core end face of one or more output fibers, such that a portion of the output optical signal is reflected to a photodiode chip. The photo-detector provides an indication of the optical power that is being coupled to the output fiber. With appropriate electronic control circuitry, the integrated optical component can be used to set the output optical power at a desired or required level.

The light input/output unit 10 has a first portion 10a in which light enters and exits a light input/output port 11 by an optical axis inclined with respect to the predetermined axis C, and a second portion 10b in which light enters and exits a light input/output port 12 by an optical axis inclined with respect to the predetermined axis C. A light entry/exit angle of the light input/output port 11 with the predetermined axis C as a reference and a light entry/exit angle of the light input/output port 12 with the predetermined axis C as a reference differ from each other.

摘要： Through its higher refractive index, a silicon grism can be used to reduce the Described herein are systems and methods for reducing optical aberrations in an optical system to decrease polarization dependent loss. Embodiments are provided particularly to define beam trajectories through an optical switching system which reduce off-axis aberrations. In one embodiment, a silicon grism is provided for reducing the curvature of the focal plane at an LCOS device in a wavelength selective switch (WSS) such that the separated polarization states converge at the LCOS at substantially the same point along the optical axis for all wavelengths. In this embodiment, an axial offset at the LCOS device will not produce large PDL at the coupling fibers. In another embodiment, a coupling lens having an arcuate focusing region is provided to address an offset in the optical beams, such that the separated polarization states couple symmetrically to respective output fibers.

摘要： The present invention relates to devices which operate on gradient optical forces, in particular, nanoscale mechanical devices which are actuable by gradient optical forces. Such a device comprises a waveguide and a dielectric body, with at least a portion of the waveguide separated from the dielectric body at a distance which permits evanescent coupling of an optical mode within the waveguide to the dielectric body. This results in an optical force which acts on the waveguide and which can be exploited in a variety of devices on a nano scale, including all-optical switches, photonic transistors, tuneable couplers, optical attenuators and tuneable phase shifters. The waveguide can also comprise a gap such that two cantilever bridges are formed.
