Embodiment Construction

[0025] The present invention provides a simple and elegant method for distributing optical signals, which can be used in a variety of applications such as multiplexing, demultiplexing, switching, or any other need to separate, combine or direct The application of the light signal. Use of Rotatable Diffractive Optical Elements (RDOE) eliminates the need for optics such as mirrors, filters, and membranes that grow in complexity proportionally to the number of optical signals to be processed extent and cost of consumption.

[0026] Referring to each figure, figure 1 is a schematic diagram of an RDOE that switches an input optical signal emitted by a laser diode assembly to a lens coupled to an optical fiber. Provide a signal source, identified by reference numeral 10, this signal source is composed of one or more optical signals, each optical signal is associated with a specific wavelength (λ) or energy, according to the convention in this professional field, "wavelength The t...

Abstract

A method and apparatus for communication applications such as switching (add / subtract), multiplex and demultiplex are disclosed. A signal source (70, 72, 74, 76) of an input optical signal (10) is directed onto a movable diffractive optical element or MDOE (12). Each optical signal has a specific wavelength. The MDOE generates and distributes output optical signals (92, 94) between output locations (88, 90).

Description

[0001] Horizontal references to related applications [0002] This application cross-references to commonly assigned Application No. _____ (Docket No. LUC2-0271), filed on the same date, the disclosure of which is hereby incorporated by reference. Background technique [0003] Within a fiber optic network, information from an information source, in the form of an electrical signal, is converted to an optical signal, which can then be transmitted along a fiber optic cable to the desired destination, where it is converted back to an electrical signal . In the realm of contemporary Internet access, faxing, multiple telephone lines, modems and teleconferencing, incredible loads are being placed on telecommunications networks to meet the ever-increasing demand for information transmission services. Since the capacity of the required fiber optic cable is unknown, classic engineering formulas such as Poisson and Reeling have been used to calc...
