There has been a renewed interest during the last few years in the evaluation of the transverse* coupling between two parallel open waveguides in connection with integrated optics circuitry 2 ' 3 a

An expression for the coupling between lossy single-mode open waveguides was derived in Part I.

Open waveguides support modes whose phase velocity is smaller than the velocity of plane waves in the surrounding medium. Thus, no radiation takes place under normal conditions.

In multichannel communication systems, crosstalk between channels is a problem that must be considered. Typically, the crosstalk should be less than --20 dB.

T h e electron cyclotron wave has received a great deal of attention in the past year, since it forms t h e basis of a successful beam-type travelingwave parametric amplifier.

LL slow electromagnetic waves have both longitudinal and transverse electric field components.

The design, fabrication, and characterization of an amplifying transverse magnetic (TM)-mode optical waveguide isolator operating at a wavelength of 1300 nm are presented.

We report the transverse-mode dynamics of electrically-biased multi-transverse mode vertical-cavity surface-emitting lasers (VCSELs) after resonant femtosecond optical pulse injection.

We have propagated transverse sound in a magnetic field in the basal plane of UPt sub 3, with the polarization vector oriented both in the basal plane and perpendicular to it.

This paper presents a characterization method of traps in GaN HEMTs, based on the frequency dispersion of the output-admittance characterized by low-frequency S-parameter measurements.
