  • Patent number: 11095961
    Abstract: Today's communications require an effective yet scalable way interconnection of data centers and warehouse scale computers (WSCs) whilst operators must provide a significant portion of data center and WSC applications free of charge to users and consumers. At present, data center operators face the requirement to meet exponentially increasing demand for bandwidth without dramatically increasing the cost and power of the infrastructure employed to satisfy this demand. Simultaneously, consumer expectations of download/upload speeds and latency in accessing content provide additional pressure. Accordingly, the inventors provide a number of optical switching fabrics which reduce the latency and microprocessor loading arising from the prior art Internet Protocol multicasting techniques.

  • Patent number: 8941911
    Abstract: Doped fiber amplifiers (DFA) using rare-earth doping materials with linear and non-linear interactions between the optical signal to be amplified and the pump laser have become a standard element of optical telecommunications systems for multiple applications including for example extending the reach of optical links before opto-electronic conversion is required or support increased fanout. However, in many applications wherein multiple DFAs are employed the electrical power budget wherein the pump laser diode (LD) represents approximately 25% of the module power consumption directly, and closer to approximately 40-50% once the control and drive electronics for the thermoelectric cooler and LD are included. Accordingly, it would be beneficial to reduce the overall power consumption of a DFA by exploiting unused optical pump power such that multiple gain stages, within the same or different DFAs, may be driven from a single pump LD.

  • Patent number: 8937768
    Abstract: An optical component has a lens including a further optical component therein. The further optical component acts upon light propagating within a portion of the lens but not on light propagating within a second other portion of the lens. A simple configuration involves a lens having a slot for having the optical component inserted therein. Optical components including the lens with further optical component include beam splitters and beam combiners.

  • Patent number: 7440172
    Abstract: An doped fiber optical amplifier featuring an optical component having first wavelength division multiplexer, an isolator and a second wavelength division multiplexer is described. The isolator supports the propagation of optical signals within a predetermined signal wavelength range in one direction. Pump signals having a wavelength within a pump wavelength range are diverted by the wavelength division multiplexers to inhibit coupling of the pump signals with the isolator. The optical amplifier supports the use of relatively high-powered optical pump lasers. The optical component is optically disposed between different lengths of doped fiber and serves to reduce optical noise within the amplifier.
