In addition, stabilized frequency combs can be coherently combined with other stable signals, including other stabilized frequency combs, to synthesize optical pulse trains with pulse durations of as little as a single optical cycle. Such a coherent combination can be achieved via orthogonal control, using balanced optical cross-correlation for timing stabilization and balanced homodyne detection for phase stabilization. | 2014-07-03 |
20140185636 | Modulation of Vertical Cavity Laser (VCSEL) For Enhanced Range of Multi-Modal Fiber Communication - Technologies are described for enabling VCSELs to transmit phase or frequency modulated signals, which may have a substantially smaller transmission bandwidth and are more robust to transmission in a highly dispersive media such as multi-mode fibers. By applying an electric, magnetic, or electromagnetic field across one or more reflector layers of the VCSEL, a refractive index of the reflector layer(s) may be modified. The VCSEL may then be excited and the laser beam generated by the VCSEL phase-modulated by modifying a magnitude of the applied field. | 2014-07-03 |
20140185637 | METHOD AND APPARATUS FOR ACTIVE VOLTAGE REGULATION IN OPTICAL MODULES - A method and apparatus for active voltage regulation in optical modules utilize a voltage regulator to change the supply voltage provided to laser diode driver and receiver electronics to optimize module performance over temperature. The ambient temperature of the module is monitored. The outputs of the voltage regulator are controlled to provide voltages that are optimized with respect to temperature for the integrated circuits in the optical module. This control is implemented via a temperature sensitive feedback or a control input from a microcontroller with a temperature monitor input. The supply voltage is optimized to minimize the voltage required to achieve acceptable performance at a given temperature. Minimizing the supply voltage lengthens the lifetime of the integrated circuit and the optical module. The voltage regulator provides higher than standard supply voltages to a laser diode driver to compensate for higher laser voltage at low temperatures. | 2014-07-03 |
