Abstract: The system and method of integrated seed and high power pump source generates two wavelengths outside the effective gain bandwidth of a single gain medium without using two unique pump sources in a fiber amplifier train. The system and method uses a single pump power oscillator that passes a seed wavelength with no loss and minimal amplification to pump integrated amplifiers in both directions (forward and backward) resulting in amplification of the seed wavelength.

Abstract: A tag operates in an environment where transmitted interrogators are not possible or desired. High-efficiency diode rectifiers and low-power oscillators are used in combination with an energy storage element and hysteretic switch. The combination of multi-diode rectifier, low power tunnel diode oscillator, energy storage element and hysteretic switch allow for nanowatt levels of received RF power to be stored to produce micro-watts of RF transmit power. The device trickle charges off of ambient RF radiation until enough energy is stored for transmission.

Abstract: A Mersenne-Cassegrain telescope provided in a single block of glass in which opposed parabolic elements are precision milled through diamond turning of a glass boule, with the magnification power of the telescope determined by the differences in focal length between the two parabolas. The result is a volumetrically small telescope with pre-aligned surfaces that are maintained by the structural rigidity of the glass itself and in which thermal coefficients of expansion, vibration and the like have no effect due to the single glass element structure.

Abstract: A method and system for processing a signal in the RF environment is disclosed. The method includes using an Analog Radio Frequency Memory (ARFM) to store an analog amplitude representation of the signal in the form of elemental charge packets. The stored signal is played back by converting the elemental charge packets back to their representative voltages to rejuvenate the original signal.
