  • Patent number: 8346084
    Abstract: An optical device for a wavelength division multiplexing system has a telecentric lens system and a signal-processing optical element, where the signal-processing optical element performs switching, attenuation, or other optical signal processing for the optical device. The telecentric lens system acts as a self-compensating optical system to minimize sensitivity of the optical device to unwanted displacement of an input image from the optical axis of the optical device. The optical device may include multiple telecentric lens systems, in which case the optical device is also less sensitive to precise alignment between the telecentric lens systems.

  • Patent number: 8326153
    Abstract: A tunable dispersion compensator (TDC) is tuned from a first dispersion setpoint to a second dispersion setpoint while maintaining continuity of the dispersion. The dispersion tuning follows a pre-determined trajectory in the time domain, so that continuity of the optical dispersion across the channel optical bandwidth is maintained while minimizing all other TDC-induced optical impairments during a tuning period.

  • Patent number: 8325193
    Abstract: One embodiment of the invention sets forth a mechanism for controlling the initialization order of an iGPU and a dGPU in a hybrid graphics processing environment to ensure that the iGPU is recognized by the operating system as the primary GPU. When the device initialization request associated with the dGPU is received, the interface module determines whether the iGPU has already been initialized. If the iGPU has already been initialized, then the interface module transmits the device initialization request to the dGPU driver for dGPU initialization. However, if the iGPU flag indicates that the iGPU has not yet been initialized, then the interface module terminates the device initialization request and transmits an initialization failure notification to the operating system. In such a manner, the dGPU is initialized only after the iGPU has previously been initialized, thereby ensuring that the iGPU is recognized by the operating system as the primary GPU.

  • Patent number: 8320419
    Abstract: A high power laser source comprises a bar of laser diodes having a first coefficient of thermal expansion CTEbar on a submount having a second coefficient CTEsub and a cooler having a third coefficient CTEcool. The submount/cooler assembly shows an effective fourth coefficient CTEeff differing from CTEbar. This difference leads to a deformation of the crystal lattice of the lasers' active regions by mechanical stress. CTEeff is selected to be either lower than both CTEbar and CTEcool or is selected to be between CTEbar and CTEcool. The submount may either comprise layers of materials having different CTEs, e.g., a Cu layer of 10-40 ?m thickness and a Mo layer of 100-400 ?m thickness, or a single material with a varying CTEsub. Both result in a CTEsub varying across the submount's thickness.

  • Patent number: 8294980
    Abstract: A delay line interferometer is configured with a liquid-crystal (LC) tuning element as a phase modulator for demodulating a phase-modulated input signal. The LC tuning element allows for quickly tuning the phase difference between two optical signals separated from the phase-modulated input signal, so that the two optical signals can be coherently recombined to interfere with each other and produce one or more intensity-modulated optical signals. In some embodiments, the LC tuning element is configured to reduce polarization-dependent frequency shift without the use of additional high-precision optical elements and/or coatings.
