    Abstract: A high-power external cavity laser source is described. The laser source includes a free space external cavity. At least two multimode optical gain elements are positioned in the cavity. Each gain element generates multimode optical radiation having one of at least a first and a second wavelength and one of at least a first and a second free space optical path, respectively. In another embodiment, at least two optical fiber gain media are positioned in at least two respective free space optical paths and each gain media generates optical radiation having one of at least a first and a second wavelength, respectively. An optical element is positioned in the cavity such that its focal plane is substantially located at the at least two optical gain elements and such that it intercepts the at least two respective free space optical paths. A dispersive element is positioned in the at least two optical paths. A partially reflecting element is also positioned in the at least two optical paths. The partially reflecting element and the gain media together form a free space laser cavity that defines the at least first and second wavelength. In operation, the partially reflecting element transmits an overlapping or coaxial beam comprising radiation having the at least first and second wavelength.

    Abstract: A burst-mode optical receiver and a timing control method are provided. The receiver receiving the burst-mode optical signal includes a transimpedance amplifier (TIA) for receiving a single current information signal and converting the single current information signal into a single voltage signal, a differential signal converter for converting the single voltage signal, received from the TIA, into differential signals, and an automatic offset control limiting amplifier (AOC-LA) for automatically controlling and amplifying an offset of the differential signals. The receiver further includes a gain controller for generating a gain value control signal based on an intensity of a burst packet of the single voltage signal to control a gain value of the TIA, and a burst detector for receiving the differential signals, detecting burst packets, and generating a burst detection signal for the start timing of each of the burst packets.

    Abstract: The invention relates to firearms and especially shotguns as well as devices or mechanisms for reducing felt recoil. In particular, the invention relates to a gas-operated device to reduce felt recoil using a recoil suppressing mass, or recoil mass, to create a counter-acting force to the recoil force. The recoil mass moves in response to the gas pressure in the barrel after firing, and more particularly the control of the flow of gas into a chamber to force the recoil mass to move and generate a recoil suppressing force. In one aspect, incorporating the gas-operated device in a firearm can improve the operator's control of the firearm and measurably reduces felt recoil and/or muzzle climb

    Abstract: Disclosed is a clock phase aligning apparatus capable of synchronizing a clock signal in the middle of an upstream burst mode data bit in an optical line terminal of a passive optical network. The clock phase aligning apparatus effectively aligns a phase of a clock signal with a phase of data during an overhead period of burst mode packet data through an over-sampling scheme and a digital scheme. Burst mode data signals are subject to an over-sampling through a high speed continuous mode analog circuit and then converted into low speed parallel signals through a parallel conversion unit. Such low speed parallel signals are processed with respect to sampling patterns through a digital look-up scheme in a logic circuit device such that the phase of data is arranged with the phase of a clock signal during a limited bit stream specified in a burst mode preamble timing.

    Abstract: A transimpedance amplifier for a burst mode optical communication converts a burst current signal into differential output voltage signals. Using a multi-level digital AGC mechanism, the transimpedance amplifier is rapidly adapted to a burst signal whose amplitude varies in a wide range. By using an adaptive level detection method, a multi-level digital AGC can be implemented without using ADC. In addition, because the transimpedance amplifier uses a selective reset generation scheme that performs a reset operation for itself after a high power burst, a burst mode operation can be performed without external reset signals. Accordingly, the transimpedance amplifier can be integrated with an optical detector within a TO-can. Furthermore, the transimpedance amplifier can have the burst mode capability and the best sensitivity.
