Amplifying optical spring effect in an optical cavity with an optical parametric amplifier
Optics LettersWe demonstrate the ability to manipulate the optical spring (OS) effect by integrating an optical parametric amplifier (OPA) into an optical cavity. The resonance profiles of the OPA cavity were measured as the OPA phase was tuned to both amplification and de-amplification modes.

Recent progress on an erbium-doped optical fiber amplifier (EDFA) pumped with a 0.98 micron laser diode is reported. An erbium-doped fiber with a very high gain coefficient of 11.0 dB/mW has been achieved using an extended VAD method. A high power 0.98 micron laser diode with a strained-layer InGaAs quantum well laser structure has been developed as ...

Optical Amplifier Applications
Proceedings IEEE SOUTHEASTCON '97. 'Engineering the New Century', 2005Optical amplifiers are beginning to find wide application in fiber optic communication systems. They are being used as power amplifiers in transmitters to increase power budget in point-to-point links, and to compensate for splitting loss in distribution networks.

Semiconductor optical amplifiers
Conference Proceedings LEOS'96 9th Annual Meeting IEEE Lasers and Electro-Optics Society, 2002Polarization insensitive semiconductor amplifiers are important devices for many applications. Their small size, high-gain, and ability to be turned on and off fast offer interesting possibilities for photonic switches. We have used a design to implement polarization insensitivity.

Optical amplifiers for communication
Optical Fiber Communication, 1987Optical amplifiers are an important component for future communication systems as they provide direct linear amplification and can be used as an optical switch or a nonlinear element for optical processing. The amplifiers may be based on semiconductor lasers or optical fibers.

Semiconductor optical amplifiers
Proceedings of the IEEE, 1992Reviews some of the recent advances in semiconductor laser amplifiers and highlights some of the device and system issues connected with the use of optical amplifiers. Particular attention is given to noise properties, system applications (i.e. in-line amplifiers, power amplifiers, and receiver preamplifiers), and nonlinear effects.

Dielectric film optical amplifier
Applied Optics, 1990An optical amplifier is described using an active dielectric film. Electromagnetic scattering from this type of active film has been studied in the past using infinite plane waves. The use of unbounded fields resulted in scattering coefficients that approached infinity at resonance.

Optical parametric amplifiers constitute a category of amplifiers whose operation is based on a physical process that is quite distinct from other amplifiers discussed in the preceding chapters. The major difference is that an atomic population is not transferred to any excited state of the system, in the sense that the initial and final quantum ...
