Amplified-spontaneous-emission feedback circuit scheme for optical measurement with improved optical power resolutions
نویسندگان
چکیده
We proposed a novel optical power measurement scheme, which significantly improved resolution (OPR) by implementing an amplified-spontaneous-emission feedback circuit (ASEFC) ahead of conventional meter. The scheme was named “ASEFC scheme.” ASEFC operates in regions near the lasing threshold. OPR characteristics were clarified experimentally. demonstrated OPRs loss component. less than 0.00014 dB, and sensitivity greater 67, at display 0.01 dB for

WDM optical steganography based on amplified spontaneous emission noise.
We propose and experimentally demonstrate a wavelength-division multiplexed (WDM) optical stealth transmission system carried by amplified spontaneous emission (ASE) noise. The stealth signal is hidden in both time and frequency domains by using ASE noise as the signal carrier. Each WDM channel uses part of the ASE spectrum, which provides more flexibility to apply stealth transmission in a pub...
متن کاملOptical Klystron Enhancement to Self Amplified Spontaneous Emission at FERMI
The optical klystron enhancement to a self-amplified spontaneous emission free electron laser has been studied in theory and in simulations and has been experimentally demonstrated on a single-pass high-gain free electron laser, the FERMI FEL-1, in 2014. The main concept consists of two undulators separated by a dispersive section that converts the energy modulation induced in the first undulat...
متن کاملOptical antenna enhanced spontaneous emission.
Atoms and molecules are too small to act as efficient antennas for their own emission wavelengths. By providing an external optical antenna, the balance can be shifted; spontaneous emission could become faster than stimulated emission, which is handicapped by practically achievable pump intensities. In our experiments, InGaAsP nanorods emitting at ∼ 200 THz optical frequency show a spontaneous ...
متن کاملBrillouin optical correlation domain analysis with 4 millimeter resolution based on amplified spontaneous emission.
A new technique for Brillouin scattering-based, distributed fiber-optic measurements of temperature and strain is proposed, analyzed, simulated, and demonstrated. Broadband Brillouin pump and signal waves are drawn from the filtered amplified spontaneous emission of an erbium-doped fiber amplifier, providing high spatial resolution. The reconstruction of the position-dependent Brillouin gain sp...
متن کاملAmplified Spontaneous Emission'
We review the coherence properties of the self-amplified spontaneous emission (SASE). Temporally, SASE is similar to the spontaneous undulator radiation except that the spectral bandwidth is about ten times narrower compared with typical undulator radiation. The situation is quite different in the transverse dimension, where SASE is fully coherent. INTRODUCTION Several laboratories are pursuing...
