Abstract: A grating assisted optical waveguide for use in free space optical detection is disclosed. High speed, high sensitivity, large field of view, and relaxed tolerance on alignment are enabled. The grating converts a free space incoming optical beam into guided mode. Converted optical signals propagate along the waveguide, and can be directed to an optical detector. As such, the optical intensity at the active area of the detector is increased significantly. A number of optical beam converter gratings for free space light collection can be used, including linear and ring structure gratings, chirped gratings, and multilayer gratings. Such a grating assisted optical waveguide can be used, for example, in a digital wireless multimedia system, where digital content is wirelessly transmitted from a source to a target destination, such as home-based video and audio entertainment systems.

Abstract: Embodiments provide single fiber bidirectional HDCP modules. A signal fiber module includes at least one laser and at least one detector and a waveguide combiner/splitter. An optical fiber is used as a cylindrical lens in order to partially collimate in the vertical axis the optical signals entering and leaving branches of a waveguide. The branches of the waveguide have lens-shape interfaces in order to at least partially collimate in the horizontal axis the beams entering and leaving the waveguide. Each branch of the waveguide tapers toward a join-section of the waveguide. At the join section, the cross-section of a laser branch is smaller than the cross-section of a detector branch. If more than one detector is present in a module, the cross-sections of the detector branches differ from each other. If more than one laser is present in a module, the cross-sections of the laser branches differ from each other.

Abstract: Techniques that provide cost effective optical fiber communication links for HDCP transmission systems and the like are provided. A single fiber for bidirectional communication is enabled, without wavelength selective unit to achieve the HDCP transmission. One embodiment of the present invention has a forward channel using a light source (e.g., VCSEL at about 850 nm) in the GHz modulation level (e.g., 1 GHz or greater), and a corresponding photodetector. The backward channel has a light source (e.g., LED at 630 nm) in the MHz modulation level (e.g., 10 MHz or less), and a corresponding photodetector. One application is for realizing a home entertainment system (e.g., DVD player and high definition television) that employs an HDCP-enabled communication link to transmit copy restricted digital content.

Abstract: Systems devices and methods in accordance with the invention impart high strength index of refraction patterns to photosensitive optical devices, such as Bragg gratings written in optical fibers. A length of small diameter fiber retaining photosensitivity is fabricated by flame elongation of an optical fiber precursor having dopant containing cladding, using a diffuse, low velocity inverted flame that does not introduce water, OH or H2 into the fiber. By varying the flame velocity during each scan the fiber is diminished to a small, uniform diameter, waist region. Photosensitivity is preserved and enhanced by exposure of the prepared waist region to scanning actinic illumination within an in-diffusing environment of pressurizing hydrogen or deuterium, and controlling the exposure to optimize the photo-induced index change.

Abstract: An add/drop filter for optical wave energy incorporates a Bragg grating in a very narrow waist region defined by merged lengths of elongated optical fibers. Light is propagated into the waist region via adiabatically tapered fibers and is transformed from two longitudinally adjacent fibers into two orthogonal modes within the air-glass waveguide of the waist and reflected off the grating from one fiber into the other. The geometry of the waist region is such that the reflected drop wavelength is polarization independent, without lossy peaks in the wavelength band of interest. Additionally, back reflection are shifted out of the wavelength band of interest. High strength gratings are written by photosensitizing the waist region fibers by constantly in-diffusing pressurized hydrogen or deuterium. For narrow spectral bandwidth gratings, dimensional variations must be minimized or compensated, and the grating is apodized by both a.c. and d.c. variations in writing beams at a net constant power.
