摘要： Improved methods and systems for routing and aligning beams and optical elements in an optical device include a multiplexing device and/or a demultiplexing device, which includes an optical alignment element (OAE). The OAE can be configured to substantially compensate for the cumulative alignment errors in the beam path. The OAE allows the optical elements in a device, other than the OAE, to be placed and fixed in place without substantially compensating for optical alignment errors. The OAE is inserted into the beam path and adjusted. This greatly increases the ease in the manufacturing of optical devices, especially for devices with numerous optical elements, and lowers the cost of manufacturing. The multiplexing and/or demultiplexing device can reside within a standard small form factor, such as a GBIC. The devices fold the paths of the traversing beams with a geometry which allows a small package.

摘要： An optical subassembly utilizes a core with a first, second, and third faces. The first and second faces are coupled, non-parallel, and non-co-planar for changing a path of a beam, and their intersection defines an axis. Filters are coupled to the third face. The light path traverses between the first or second face and each filter such that, at each filter, no portion of the light path interferes with any other portion of the light path. The light path also traverses the core in a direction along the axis. This is facilitated by the light path traversing an external surface of a filter at an angle. The device includes adjustable ports residing at the same side of the device. Filters are coupled to the core and optically coupled to the adjustable ports. The light path travels down the core and exit or enter the device via the adjustable ports.

摘要： An optical communication device is provided. One or more pairs of matched diode lasers are located at first and second stations and are connected by a fiberoptic cable. A bit stream is applied to the output beam of the laser or lasers at the first station. The output beam carrying the bit stream passes through the fiberoptic cable to the matched laser or lasers at the second station and combine with the output beam of the receiving laser cavity at the second station to form a combined output beam. The power of the combined output beam is measured and time-dependent changes in the measured output power of the combined output beam is used to read the bit stream. Multiple pairs of matched lasers using different wavelengths may be positioned at the first and second stations. In yet another form of the invention, a frequency injection technique is utilized to modulate the output beam and a deconvolution system is provided to read the bit stream or streams.

摘要： An apparatus and method are provided for determining the position of a reflective target surface using one or more laser cavities. A transmitting laser cavity produces a stable resonator output beam which is modulated with a compound beam pattern including a first wave of frequency f.sub.1 and a second wave of frequency f.sub.2. The reflected compound modulated beam enters a receiving laser cavity and fundamental and harmonic waves f.sub.1 and f.sub.2 are generated in the receiving laser cavity. The power of the compound modulated output beam of the receiving laser cavity is measured by a photodiode and a deconvolution system is connected to the photodiode for filtering the fundamental frequency of f.sub.1 and the second harmonic of wave f.sub.2. Time-dependent changes in the measured power of the modulated compound output beam are used to derive positional information of the target. In another form of the invention, two or more matched lasers form transmitting and receiving cavities and changes in the measured output power of the receiving cavity are used to derive positional information of the target. In another form of the invention, an amplitude modulated scheme is utilized wherein the coherence length of the output beam is reduced and time-dependent changes in the measured power of the modulated amplitude output beam in the receiving laser cavity are used to derive positional information of the target. [In another embodiment of the invention, a pair of matched diode lasers form the transmitting and receiving laser cavities, and wherein the output of the transmitting laser cavity is electronically modulated and wherein the impedance of the receiving diode laser is measured and time-dependent changes in the measured impedance are used to derive positional information of the target.]

摘要： An optical disk reader or read/write system for CD or DVD formats. First and second laser diodes operating at different wavelengths have their output beams collimated and directed at a single element objective lens, and are then reflected off the disk back through the lens to a photodetector. The single element objective lens has a central aperture zone and an outer aperture zone, the central zone being profiled to operate at a first numerical aperture at approximately 0.45 and the output beam of the first laser diode is confined to the central aperture zone. The outer aperture zone together with the central aperture zone are profiled to operate at a second numerical aperture, for example 0.60 wherein the output beam of the second laser diode has ray fans extending across the full aperture of the single element objective lens. A diffractive is formed on one surface of the single element objective lens and provides sufficient aspheric surface power for spherical aberration correction as well as correction for spherochromatism. The diffractive also provides sufficient correction for spherical aberration and spherochromatism that the single element objective lens achieves diffraction-limited image quality for both CD and DVD formats.

摘要： An optical sensing apparatus is provided for sensing changes of index of refraction and sensing changes of length of a fiberoptic cable, for example. A transmitting laser cavity produces a stable-resonator output beam which is modulated with a compound beam pattern including a first wave of frequency f.sub.1 and a second wave of frequency f.sub.2. The reflected compound modulated beam enters a receiving laser cavity and fundamental and harmonic waves f.sub.1 and f.sub.2 are generated in the receiving laser cavity. The power of the compound modulated output beam of the receiving laser cavity is measured by a photodiode and a deconvolution system is connected to the photodiode for filtering the fundamental frequency of f.sub.1 and the second harmonic of wave f.sub.2. Time-dependent changes in the measured power of the modulated compound output beam are used to derive changes of index of refraction or changes in length. In another form of the invention, two or more matched lasers form transmitting and receiving cavities and changes in the measured output power of the receiving cavity are used to derive the desired information.

摘要： A low cost compact 3-port single-channel OADM with improved optical isolation is provided in which the I/O fibers and add/drop fiber are arranged on the same side. The 3-port OADM includes a 3-fiber pigtail and an angled reflector that together eliminate the second fiber collimator—one set of lenses and ferrules. The reflector is positioned behind and at angle to the free-space filter such that the add/drop optical signals are reflected back through the collimating lens to the appropriate fiber. In a drop filter, a signal is dropped from the optical signal on the input fiber and reflected back to the add/drop fiber. In an add filter, a signal is inserted from the add/drop fiber and reflected back to the output fiber. A 4-port OADM can be made by fiber-splicing a pair of 3-port OADMs.
