We have used a two quantum-well GaInNAs semiconductor saturable absorber mirror (SESAM) with a high power InP-based semiconductor disk laser to obtain a 2 GHz mode locked OP-VECSEL laser with a pul

In multimode optical fibers, light pulses are carried by many modes.

We demonstrate a mode scrambler using CO2-laser inscribed long-period gratings for mixing 3 spatial modes.

Interferometer-type resonators that are used in optical masers are inherently multimode devices.

We demonstrate a mode selective photonic lantern with a graded index core, which modes are a better match when splicing to graded index transmission fiber compare to those from a photonic lantern w

We consider quantum frequency conversion using four-wave mixing Bragg scattering and the prospects for multiplexing using the temporal modes.We find that there is an optimal strength parameter, but

A mode stabilization technique for waveguide grating router lasers which allows suppression of multi-longitudinal mode operation while simultaneously decreasing the laser chip size and increasing t

We propose all-fiber mode multiplexer composed of two consecutive LP11 mode selective couplers that allows for the multiplexing of LP01 mode and two-fold degenerate LP11 modes.

This paper introduces a new design approach for multi-element MIMO antennas that exploit the mode-based technique and proposes a novel antenna structure capable of achieving polarization and patter

We present a tutorial discussion of high speed lasers, light emitting diodes and amplifiers in which index guiding is used to provide fundamental transverse mode behavior.
