    摘要: An optical subassembly includes an opto-electronic device, an optics block and a spacer, separate from the optics block and providing spacing between the opto-electronic device and the optics block. The opto-electronic device, the optics block and the spacer are aligned and bonded together. This subassembly is particularly useful when coupling light between the opto-electronic device and a fiber. The optical subassembly may also include an opto-electronic device, an optics block and a sealing structure surrounding the opto-electronic device. The opto-electronic device, the optics block and the sealing structure are aligned and bonded together.

    摘要: A power monitor for a light emitter emitting from a single face creates a monitor beam by deflecting a portion of the application beam and further manipulating the monitor beam to allow more efficient use of the monitor beam. For example, the monitor beam may be collimated to allow an increase in spacing between the light emitter and a detector for sensing the monitor beam. Alternatively or additionally, the monitor beam may be focused to allow use of a smaller detector and of a smaller percentage of the application beam. The diffractive element deflecting the beam may be either transmissive or reflective. The additionally manipulation of the monitor beam may be provided by the same diffractive element which deflects the beam, which is particularly useful when the diffractive element is reflective, and/or by additional optical elements.

    摘要: A beam homogenizer that minimizes undesired intensity variations at the output plane caused by sharp breaks between facets in previous embodiments. The homogenizer includes a hologram made up of irregularly patterned diffractive fringes. An input beam illuminates at least part of the hologram. The hologram transmits a portion of the input beam onto an output plane. In doing so, the energy of the input beam is spatially redistributed at the output plane into a homogenized output beam having a preselected spatial energy distribution at the output plane. Thus, the illuminated portion of the output plane has a shape predetermined by the designer of the homogenizer.

    摘要: Gray scale masks used to create optical elements are formed. Desired gray scale patterns may be created by varying the thickness of a light absorbing layer. Such variations in thickness may be created using multiple binary masks. Desired gray scale patterns may also be created on a computer using available software and then imaged onto film or a glass film plate. Direct contact or proximity printing is then used to transfer the true gray scale pattern onto photoresist. The photoresist is then etched, thereby forming the desired pattern therein. All portions of the desired pattern are simultaneously formed in the photoresist. The etched photoresist is then used to photolithographically fabricate either the optical element itself or a master element to be used in injection molding or other replication techniques. The gray scale mask itself may be used repeatedly to generate photoresists. The imaging is particularly useful for forming optical elements having a plurality of arrays of refractive elements.

    摘要: An improved optical system is disclosed for projecting light in the form of an image to a remote target. The laser light source and a holographic optical element are mounted together in optical alignment. The optical element is created using iterative discrete computer encoding for optimum efficiency. In alternate embodiments, the diffractive optical element has a collimating lens encoded into the grating levels and it also performs soft aperture circularizing using either amplitude or phase control over the coherent light. An embossed diffractive optical element laminated to an injection-molded refractive element is also disclosed.
