  • Patent number: 9164201
    Abstract: A lens (1) includes a plurality of optical surfaces (S1, S2) each of which is made up of an alternation of active zones (ZA1, ZA2) and separation zones (ZS1, ZS2). The active zones of one of the surfaces are situated beside the separation zones of the other surface. The shape of one at least of the optical surfaces is then adapted into the separation zones in order to augment the acute angles that are situated at the convergence of active zones and separation zones. The lens can thus be made with improved accuracy with respect to a target optical function.

  • Patent number: 9134526
    Abstract: This disclosure provides systems, methods and apparatus for providing multiple dielectric coatings for a shutter assembly. The multiple dielectric coatings include an outer dielectric coating and one or more inner dielectric coatings. The outer dielectric coating has an electrical trap density that is lower than electrical trap densities of the one or more inner dielectric coatings. The lower electrical trap density reduces the amount of charge buildup over various surfaces of the shutter assembly. This reduction in charge buildup also reduces electrostatic forces that may cause incorrect operation of the shutter assembly.

  • Patent number: 9116367
    Abstract: A transmitter optical module implemented with an electro-absorption (EA) modulator is disclosed. The module includes an EA driver comprising a signal detector, an offset controller, and a driver circuit. The signal detector detects the existence of the modulation signal input thereto. The offset controller provides to the driver circuit the first offset to shift the cross point of the output of the driver circuit higher when the modulation signal exists; while, the second offset when the modulation signal disappear. The second offset lowers the output of the driver circuit to prevent the excess optical output of the transmitter optical module.
