Temporally Coherent Depolarizer And A Polarization Transformer

View page
US Patent:
7110623, Sep 19, 2006
Filed:
Jan 23, 2004
Appl. No.:
10/763529
Inventors:
Ralph Kalibjian - Livermore CA, US
International Classification:
G02B 6/34
G02B 27/28
G02B 5/30
G02F 1/01
US Classification:
385 11, 385 36, 359251, 359488, 359496
Abstract:
A corner cube utilized for both a polarization transformer and a depolarizer requires a special glass for the corner cube. For the transformer a polarized probe beam irradiates only one facet of the corner cube off-axis to vertex, whereas for the depolarizer a circularly polarized beam irradiates all three facets symmetrically on-axis to the cube vertex. The collimated output beam from the corner cube has a hexad pattern where alternate hexads correspond to CW (clockwise) and CCW (counter-clockwise) rotations in sequential reflections from the corner cube facets. CW and CCW hexad regions comprising the depolarized beam differ in phase by 0. 8π radians. A dielectric layer pattern of alternate hexads deposited on the output port of a beam director in registry to the depolarized beam pattern compensates for the leading phase of the CCW hexads thus equalizing the overall phase-front of the beam and thereby resulting in a temporally-coherent depolarized beam.

Corner Cube Depolarizer

View page
US Patent:
7254288, Aug 7, 2007
Filed:
Oct 11, 2005
Appl. No.:
11/247020
Inventors:
Ralph Kalibjian - Livermore CA, US
International Classification:
G02B 6/34
G02B 5/04
G02B 27/28
US Classification:
385 11, 385 36, 359488, 359834
Abstract:
The depolarizer utilizes a commonly available BK7 glass corner cube to transform linearly polarized light into depolarized light with 100% conversion efficiency. The low-cost corner cube is a unique optical element that greatly simplifies the means for producing completely depolarized light as compared to other current methods and techniques. The corner cube is irradiated uniformly, but at non-normal incidence for a tilt angle of about 9 with respect to the input light beam path. The polarization orientation angle of the input beam in combination with the tilt angle and tilt-axis orientation of the corner cube must be optimized in order to make the Stokes polarization parameters equal to zero, and thereby generating the depolarized light beam A bidirectional beam director steers the retro-reflected depolarized light beam from the corner cube to the output port of the depolarizer.

Non-Linear Optical Crystal Vibration Sensing Device

View page
US Patent:
53355482, Aug 9, 1994
Filed:
Jun 19, 1992
Appl. No.:
7/901289
Inventors:
Ralph Kalibjian - Livermore CA
Assignee:
The United States of America as represented by the Department of Energy - Washington DC
International Classification:
G01H 100
G01H 900
US Classification:
73655
Abstract:
A non-linear optical crystal vibration sensing device (10) including a photorefractive crystal (26) and a laser (12). The laser (12 ) produces a coherent light beam (14) which is split by a beam splitter (18) into a first laser beam (20) and a second laser beam (22). After passing through the crystal (26) the first laser beam (20) is counter-propagated back upon itself by a retro-mirror (32), creating a third laser beam (30). The laser beams (20, 22, 30) are modulated, due to the mixing effect within the crystal (26) by vibration of the crystal (30). In the third laser beam (30), modulation is stable and such modulation is converted by a photodetector (34) into a usable electrical output, intensity modulated in accordance with vibration applied to the crystal (26).

Ultra-Fast Framing Camera Tube

View page
US Patent:
42438780, Jan 6, 1981
Filed:
Jul 7, 1977
Appl. No.:
5/813762
Inventors:
Ralph Kalibjian - Livermore CA
International Classification:
H01U 3150
US Classification:
250213VT
Abstract:
An electronic framing camera tube features focal plane image dissection and synchronized restoration of the dissected electron line images to form two-dimensional framed images. Ultra-fast framing is performed by first streaking a two-dimensional electron image across a narrow slit, thereby dissecting the two-dimensional electron image into sequential electron line images. The dissected electron line images are then restored into a framed image by a restorer deflector operated synchronously with the dissector deflector. The number of framed images on the tube's viewing screen is equal to the number of dissecting slits in the tube. The distinguishing features of this ultra-fast framing camera tube are the focal plane dissecting slits, and the synchronously-operated restorer deflector which restores the dissected electron line images into a two-dimensional framed image. The framing camera tube can produce image frames having high spatial resolution of optical events in the sub-100 picosecond range.

Optical-Hybrid Etalons For Simultaneous Phase- And Polarization-Diversity Operations

View page
US Patent:
59033932, May 11, 1999
Filed:
Dec 4, 1997
Appl. No.:
8/985108
Inventors:
Ralph Kalibjian - Livermore CA
International Classification:
G02B27/10
US Classification:
359618
Abstract:
Simultaneaous phase- and polarization-diversity in a coherent receiver are provided from a single-unit 90. degree. -hybrid (as shown in the upper section of FIG. 2) by combining the polarization angle and the phase angle of the input lightwave signal into an effective phase angle in the hybrid output. Thus, the number of components in the receiver is reduced as compared to conventional systems, thereby simplifying the processing network operations in the coherent detection system. The hybrid is implemented by the use of a quarter-waveplate (QWP)/etalon 30 in conjunction with an input QWP 32. The linearly polarized signal beam transmitting through the QWP 32 (of variable polarization angle) is incident to the 2-face 14 of the QWP/etalon 30. The linearly-polarized local-oscillator beam 18 is incident on the 1-face 12, and is aligned co-directionally to the reflected beamlets 20 of the signal beam 28. The proper orientation of the waveplates 30 and 32 and the proper selection of the etalon phase angle are key elements in providing simultaneous phase- and polarization-diversity in the single-unit 90. degree. -hybrid.
