High rate optical amplification
1968 Edition, Volume 4, May 1, 1968 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The equations of Q switching are reexamined for a homogeneously broadened two-level material. It is shown that inertial effects in the material polarizability may play an important role in Q switching of lasers of narrow material linewidth. It is further shown that it is...

Versatile waveguide design for optical amplification
2001 Edition, Volume 3, January 1, 2001 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Optical amplification in novel rare-earth-doped waveguides is demonstrated. Design and measurements of an Erbium/Ytterbium co-doped glass waveguide amplifier are presented. The benefits of the design as applied to low-cost amplification are discussed.

PAM-4 Performance Optimization in Presence of Optical Amplification
2018 Edition, September 1, 2018 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A large OSNR gain is demonstrated for PAM-4 systems used in presence of optical amplification by level optimization with respect to standard intensity equispaced signals.

Low noise quantum optical amplification using an optical amplifier
2011 Edition, May 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Perfect quantum optical amplification is forbidden [1]. Either noise is added, or the amplification is not deterministic. Nondeterministic amplification is normally based on the quantum scissors device [2]. Here we propose using a standard quantum optical...

Optical amplification enhancement in photonic crystals
2011 Edition, May 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Improving and controlling the efficiency of a gain medium is one of the most challenging problems of laser Research [1]. By measuring the gain length in an opal-based photonic crystal (PhC) [2] doped with laser dye, we demonstrate that optical...

Optical Amplification for BTDM-SFSW-Based Time Transfer
2017 Edition, Volume 35, October 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Optical amplification, which is necessary for extending the distance of fiber-optic time transfer, has significant impacts on the time transfer performance. In this paper, we investigate and optimize the optical amplification for the time transfer based on...

Optical amplification for communication systems
2002 Edition, Volume 1, January 1, 2002 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The state-of-the-art of planar optical amplifier, with particular emphasis to the work of research group of the Politecnico di Bari is reported. The first two examples pertain to high gain planar waveguide amplifiers, made by erbium doped and erbium-ytterbium...

Optical amplification by dynamical gratings
1996 Edition, Volume 2, January 1, 1996 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Summary form only given. We describe in particular a density grating obtained from the interaction between a strong e.m. pump field and an atomic vapor, which allows for the amplification of a probe field. Experimental results and an interpretation are offered in this case, together...

Optically-Amplified Short-Length Analog Photonic Links
2006 Edition, October 1, 2006 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The performance capabilities of short-length analog photonic links employing optical amplification with erbium-doped fiber amplifiers are presented. Optically-amplified links are compared to their unamplified counterparts in terms of gain, noise figure,...

Optical parametric amplification
1979 Edition, Volume 15, June 1, 1979 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper presents a detailed theoretical and experimental study of optical parametric amplification. Experimental measurements in KD*P pumped at 354.7 nm and LiNbO 3 pumped at 1064 nm by a Q -switched Nd:YAG source are in excellent agreement with theory. The large...
