A semiconductor laser package including a mounting structure at least partially encapsulating a vertical cavity surface emitting laser and a photodetector. The vertical cavity surface emitting laser generating an emission along a path. The photodetector optically positioned and/or integrally formed with the vertical cavity surface emitting laser to receive a portion of the emission. An optical element is optionally positioned in the path, mounted on the mounting structure utilizing a snap-fit connection, a threaded or adhesive mounting. The mounting structure and optical element are fabricated to allow for proper z-axis alignment of the optical element relative to the laser emission aperture.

摘要:
A system for dynamically steering a light beam alters the path of a light beam using refraction. The light beam passes through multiple layers of optically transparent elastic material. Electrodes are attached to the bottom and top surfaces of the optically transparent layers. Voltages applied to the electrodes cause the optically transparent layers to deform. This deformation causes a change in the angle at which the light beam intercepts the surfaces of the optically transparent layers. The light beam is refracted based upon the angle of intercept and the index of refraction of the optically transparent layers. The direction of travel of the light beam can thus be controlled by varying the voltages across the electrodes.

A display which writes an image directly on the retina of an eye. The display includes a laser which produces a collimated light beam that is modulated with video information and is then scanned and directed through the eye pupil to produce an image on the retina. The scanning uses micro-machined mirrors, electro-optic or acousto-optic devices which are extremely small and require very low power.

A method of manufacturing a molded optical channel waveguide, having a critical internal reflection angle and an exposed surface, and affixing a holographic layer, having gratings formed therein, in overlying relationship with the exposed surface of the optical waveguide. The gratings are positioned to form an angle with the surfaces of the holographic layer such that light rays incident on an upper surface of the holographic layer and substantially normal thereto are diffracted by the gratings into the optical waveguide. Also, light waves travelling within the waveguide emanate outwardly through the holographic layer. Light generators and detectors are mounted to supply light to and receive light from the holographic layer.
