US Patent:

6473211, Oct 29, 2002

Filed:

Aug 31, 2001

Appl. No.:

09/943847

Inventors:

Thomas W. Stone - Hellertown PA

Assignee:

Agilent Technologies, Inc. - Palo Alto CA

International Classification:

H04B 1000

US Classification:

359117, 359130, 359566, 359573, 385 17

Abstract:

A switching and/or rotuing system that utilizes high efficiency switched diffractive gratings to form optical switching, interconnection, and routing networks. The diffractive gratings are electrically, optically, or otherwise switchable, so that they may be turned âoffâ (a state in which the incident beam is undeviated) or âonâ (a state in which the incident beam is diffracted to a new direction). All of the above switching and/or routing operations being accomplished in âfree space. â.

Inventors:

Thomas W. Stone - Hellertown PA

Assignee:

Agilent Technologies, Inc. - Palo Alto CA

International Classification:

G02B 526

US Classification:

359839, 359838, 359850, 359 7, 359 15, 359572, 385 16, 385 17, 385 18, 385 37

Abstract:

An optical system having at least one switched mirror for switching and routing at least one incident beam of electromagnetic radiation. The switched mirrors are controlled by a voltage source and based upon the desired controllability of the switched mirrors and wide range of switching and or routing of an optical signal can be effected. In addition by the selective placement of components with the optical system polarization effects can be controlled with the optical system to more effectively provide for subsequent signal transmission.

Appl. No.:

09/425551

Inventors:

Thomas W. Stone - Hellertown PA

Assignee:

Wavefront Research, Inc. - Bethlehem PA

International Classification:

H01J 314

US Classification:

250216, 2502081, 359652

Abstract:

An optical interconnect system having a GRIN rod lens, the GRIN rod lens having a first end and a second end, and further having a preselected length, a preselected width and a preselected index of refraction. Means are fixedly secured to the first end of the GRIN rod lens for emitting electromagnetic radiation and means are fixedly secured to said second end of said GRIN rod lens for receiving the emitted electromagnetic radiation. The GRIN rod lens forms an image of the emitting means onto the receiving means and overcomes problems associated with misalignment. Further embodiments of this optical interconnect system are capable of use in even further applications in an environment where alignment problems are at issue.

Appl. No.:

10/444797

Inventors:

Thomas A. Mitchell - Nazareth PA
Thomas W. Stone - Hellertown PA

Assignee:

Agilent Technologies, Inc. - Palo Alto CA

International Classification:

G02B 626

US Classification:

385 15, 385 16, 385 24, 385 37, 398 81, 398 84, 398 45, 398 49

Abstract:

Methods and systems that compensate for the lateral chromatic dispersion and lateral shifts induced by the propagation through a switching/routing optical system. Utilizing the methods and systems of the present invention, an output of a switching/routing optical system that produces angularly dispersed output beams is achromatized by, first, deviating the output optical beam to a direction sufficient to induce lateral chromatic aberration of the opposite sign to that produced by the switching/routing optical system; and, then, re-deviating the deviated output optical beam to a predetermined direction, where a path length of the deviated output optical beam is a length sufficient to substantially compensate the chromatic dispersion induced by the switching/routing optical system.

Agilent Technologies, Inc. - Palo Alto CA

International Classification:

G02B006/26
G02B006/00

US Classification:

385 17, 385147, 398 45, 398 49, 398130

Abstract:

An optical switching and/or routing system including a first opto-electronic assembly, a router assembly, a second opto-electronic assembly and redirecting means interposed between the router assembly and the second opto-electronic assembly. Each opto-electronic assembly includes at least one module, each module having a detector, an amplifier and a laser. During operation, the optical switching and routing system of this invention receives the input optical beams at the first opto-electronic assembly and emits a second group of optical beams from the first opto-electronic assembly. The second group of optical beams is received at the router assembly and each beam from the second group of optical beams is routed to a pre-selected location. From the pre-selected locations to which they have been routed, the second group of optical beams is redirected to the second opto-electronic assembly. The second opto-electronic assembly receives the second group of optical beams and emits the output beams.
