Abstract: The invention is based on the idea that wavelength of a laser transmitter in a WDM system can be changed in a controlled fashion by inducing an accurately pre-defined change in the cooler control current TEC. This, in turn, effects a controlled change in the heating or cooling operation of the cooler. As a result, a predetermined change takes place in the wavelength of the light generated by the laser. The temperature control circuit ensures that the laser temperature and, thus, wavelength, are maintained exactly at the new value. For each desired wavelength, a parameter set consisting of a pre-set laser temperature value, a laser power value and laser modulation bias values has been saved in storage in advance. When the laser wavelength is to be changed, the parameter values corresponding to the wavelength are retrieved from the storage and fed to the laser. Retrieval and feeding can be pre-programmed or carried out manually.

Abstract: An optical transmitter includes a transmitter support bench engaged to a printed circuit board, different semiconductor laser assemblies engaged to the transmitter support bench to emit laser beams at different laser wavelengths to carry communication signals at the different laser wavelengths, a wavelength multiplexing device engaged to the transmitter support bench and located to receive the laser beams from the semiconductor laser assemblies and to combine the different laser beams into a combined output laser beam as an output of an optical transceiver, and an optical isolator located relative to the wavelength multiplexing device to receive the combined output laser beam while preventing light propagating in a direction opposite to the combined output laser beam, thus reducing undesired optical feedback to the wavelength multiplexing device and the semiconductor laser assemblies.

Abstract: A light steering system and method for diffractive steering of electromagnetic radiation such as visible light is disclosed. Embodiments of the light steering system include leaky-mode SAW modulators as light modulator devices. The SAW modulators preferably include reflective diffractive gratings. The gratings are mounted to/patterned upon an exit face that opposes an exit surface of the SAW modulator, in one example. Steering of light signals emitted from the SAW modulators in these systems can be accomplished by varying wavelength of light signals introduced to the SAW modulators, and/or by varying frequency of RF drive signals applied to the SAW modulators. In addition, light field generators that incorporate SAW modulators of the proposed light steering system within displays of the light field generators are also disclosed.
