The reduction in penetration of the optical mode into the cladding layers in large optical cavity (LOC) laser structures offers the possibility of reducing the cladding-layer thickness. This could be particularly beneficial in GaInP-AlGaInP high-powe

Using a segmented-contact method, we have measured the optical mode loss in a series of AlGaInP 650 nm large optical cavity laser diodes with cladding layer thicknesses of 1.0, 0.5 and 0.3 µm. For the thinnest cladding layer the loss is 24 cm-1 grea

Nonlinear directional couplers (NLDCs) have great potential as the basis for all-optical switching devices. However, previous studies of semiconductor-NLDCs based on two-rib horizontal geometries have indicated that large switching powers are require

The free space radiation mode (FSRM) method is used to provide a new closed-form transcendental equation for the scalar mode propagation constant of a uniformly buried rectangular dielectric waveguide. Results are readily and rapidly obtained and are

The cause of the unusual spectral distribution, often observed in InGaAs/GaAs quantum-dot lasers, is investigated by analyzing the spectra from devices fabricated with different substrate thickness (100–400 μm). Using a Fourier transform analysis

In quantum-well edge emitting lasers at frequencies below lµm, the major intrinsic contribution to the threshold current is spontaneous radiative recombination. This is distributed over all solid angles (subject to polarisation considerations) and o
