Abstract
Abstract An optomechanical platform that provides both precise alignment and ready manufacture of optical and optomechanical components. A simplified embodiment of the invention includes a substantially symmetric cylindrical tube with an optical device at one end of the tube, a grating at another, opposite end of the tube and optics disposed between. optomechanical/optoelectronic device that is particularly well suited to WDM and imaging applications. Included is an integrated optomechanical/optoelctronic device particularly well suited to imaging and Wavelength-Division-Multiplexed (WDM) applications.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
129 words
An optomechanical platform for operating on a broad spectrum input signal carried on an optical fiber comprising: a means for providing the broad spectrum input signal in a 1-D array; a means for substantially collimating the broad spectrum input; a means for diffracting the collimated broad spectrum input into a distinct angle such that the diffracted light is directed through the collimating means a second time and onto a means for operating on the light; and the means for operating on the light which receives the light after it passes through the collimating means the second time, the light operating means including a means for selectively reflecting some or all of the light back into the collimating means, while affecting either the amplitude or phase of the reflected light.
Claim 2
Dependent Claim
129 words
An optomechanical platform for operating on a broad spectrum input signal carried on an optical fiber comprising: a means for providing the broad spectrum input signal in a 1-D array; a means for substantially collimating the broad spectrum input; a means for diffracting the collimated broad spectrum input into a distinct angle such that the diffracted light is directed through the collimating means a second time and onto a means for operating on the light; and the means for operating on the light which receives the light after it passes through the collimating means the second time, the light operating means including a means for selectively reflecting some or all of the light back into the collimating means, while affecting either the amplitude or phase of the reflected light.
Claim 3
Dependent Claim
16 words
The optomechanical platform of claim 1 wherein the reflected portion retraces the path of incident light.
Claim 4
Dependent Claim
29 words
The optomechanical platform of claim 2 wherein the selectively reflecting means is aligned by moving an input fiber relative to a device submount, prior to being fixed in place.
Claim 5
Dependent Claim
24 words
The optomechanical platform of claim 3 wherein the collimating means includes discrete, bulk optical elements or micro-optical elements integrated directly with an active device.
Claim 6
Dependent Claim
57 words
The optomechanical platform of claim 2 wherein the reflecting means selectively reflects portions of the optical signal according to optical wavelength and transmitted portions of the optical signal are directed into a means for receiving the transmitted signal situated beneath an active device, said receiving means comprising an array of detectors, optical fibers, and integrated optical waveguides.
Claim 7
Dependent Claim
18 words
The optomechanical platform of claim 1 wherein the reflected portion does not retrace the path of incident light.
Claim 8
Dependent Claim
29 words
The optomechanical platform of claim 4 wherein the selectively reflecting means is aligned by moving an input fiber relative to a device submount, prior to being fixed in place.
Claim 9
Dependent Claim
24 words
The optomechanical platform of claim 6 wherein the collimating means includes discrete, bulk optical elements or micro-optical elements integrated directly with an active device.
Claim 10
Dependent Claim
57 words
The optomechanical platform of claim 6 wherein the reflecting means selectively reflects portions of the optical signal according to optical wavelength and transmitted portions of the optical signal are directed into a means for receiving the transmitted signal situated beneath an active device, said receiving means comprising an array of detectors, optical fibers, and integrated optical waveguides.
