We present a traveling wave analysis of a general class of semiconductor lasers, which
includes multisection DFB/DBR lasers and gain-coupled DFB lasers. The analysis leads to …

A model for spontaneous emission in active dielectric microstructures is given in terms of the
classical electric field Green's tensor and the quantum-mechanical operators for the …

Over the last two decades, the search for a compact, high-power semiconductor source has
produced many designs and concepts for monolithic diode-laser arrays and optical …

The main features of quantum electrodynamics (QED) of a light-matter system embedded in
a dielectric with space-dependent refractive index are developed, and the QED formalism is …

Expanding the fields of a laser cavity in a set of orthonormal modes is a standard technique
in laser theory. Expansion in a normal mode set is also the basis of the concept of “photons” …

In end-pumped Nd: YVO_4 amplifiers, beam quality improvement is obtained both in theory
and in experiments. A theoretical model of gain-guided laser amplifier is developed by …

We describe a method for measuring the frequency fluctuation spectrum of a laser oscillator,
especially the weak noise contributions in the wings of the spectrum, and apply this method …

We present a very simple “toy model” that allows one to recover the essential mathematical
and physical features that lead to excess quantum noise and excess linewidth in lasers with …

We propose a generalized radiation-field quantization formalism, where quantization does
not have to be referenced to a set of power-orthogonal eigenmodes as conventionally …
