Super-Homogeneous Saturation of Microwave-Photonic Gain in Optoelectronic Oscillator Systems

An optically tunable wideband optoelectronic oscillator based on a bandpass microwave photonic filter.

An optoelectronic oscillator (OEO) with wideband frequency tunability and stable output based on a bandpass microwave photonic filter (MPF) has been proposed and experimentally demonstrated. Realized by cascading a finite impulse response (FIR) filter and an infinite impulse response (IIR) filter together, the tunable bandpass MPF successfully replaces the narrowband electrical bandpass filter ...

Microwave Signal Mixing by Using a Fiber-Based Optoelectronic Oscillator for Wavelength Division Multiplexed (WDM) Systems

We report on microwave signal-mixing functionality for a fiber-based optoelectronic oscillator. Two wavelength division multiplexed (WDM) channels carrying RF signals at 1320 and 1312 nm are simultaneously upconverted/downconverted by the fiber-based optoelectronic oscillator. The conversion efficiency is found to be approximately −8 dB, and the incoming signals have no effects on the local osc...

Multi-Functional SOAs in Microwave Photonic Systems

The Semiconductor Optical Amplifier (SOA) is a very attractive device for optical communication systems because of their multi-functional capability. The operation of the SOA is controlled by both the electrical and optical input signal. The SOAs have demonstrated their multi-functional capability by combining optical amplification with modulation, gating, photo-detection, dispersion compensati...

Super algebra and Harmonic Oscillator in Anti de Sitter space

The harmonic oscillator in anti de Sitter space(AdS) is discussed. We consider the harmonic oscillator potential and then time independent Schrodinger equation in AdS space. Then we apply the supersymmetric Quantum Mechanics approach to solve our differential equation. In this paper we have solved Schrodinger equation for harmonic oscillator in AdS spacetime by supersymmetry approach. The shape...
