The electrodynamics of active continuous media is applied to theoretically examine
collective spontaneous emission regimes of dipole oscillator ensembles. Recent …

Advances in optical fibre based communications systems have played a crucial role in the
development of the information highway. By offering a single mode oscillation and narrow …

На основе подхода электродинамики сплошных активных сред дан теоретический
анализ различных режимов коллективного спонтанного излучения ансамблей …

We discuss a class of lasing modes created by a spatially inhomogeneous gain profile.
These lasing modes are “extra modes,” in addition to, and very different from, conventional …

A statistical yield analysis is presented for gain-and index-coupled distributed feedback
(DFB) laser structures, allowing a comparison of their single longitudinal mode (SLM) yield …

A distributed feedback (DFB) semiconductor laser structure in which pure gain coupling can
be realized is proposed. The fabrication procedure of this structure makes use of a special …

The new paradigm of parity-time symmetry in quantum mechanics has readily been applied
in the field of optics with numerous demonstrations of exotic properties in photonic systems …

The intensity noise of a gain coupling (GC) distributed feedback (DFB) laser under the
influence of external optical feedback was measured. As a whole, the GC DFB laser was …

Lasers used for space communication, lidar, and laser detection in space-air-ground
integration applications typically use a traditional 1550 nm band tunable distributed …

We build on former results from our work on parity-time symmetric gratings implemented in
1550 nm distributed-feedback laser diodes to address the design issues raised by the first …
