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

1. 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.

2. The optomechanical platform of claim 1 wherein the reflected portion retraces the path of incident light.

3. 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.

4. 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.

5. 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.

6. The optomechanical platform of claim 1 wherein the reflected portion does not retrace the path of incident light.

7. 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.

8. 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.

9. 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.
