We report, for the first time, the experimental confirmation of the phase relationships between the output images of 1/spl times/4 and 1/spl times/8 multimode interference (MMI) splitters. Interference data is obtained using a shearing type near-fiel

We report on low-loss, alignment-tolerant coupling between a single-quantum-well (SQW) GaAs-AlGaAs laser and a cleaved single-mode fiber. The laser was fabricated using conventional growth and processing techniques, and did not involve any regrowth.

We have used a combination of experimental techniques and a numerical method based on a waveguide model to demonstrate low-modal reflectivity antireflection coatings on semiconductor lasers. Our approach does not require a detailed knowledge of the l

In this paper, we propose and demonstrate a simple GaAs-AlGaAs SQW laser employing conventional growth and processing techniques. In this laser, the transverse spot size has been increased by the use of a diluted waveguide (Al mole fractions are grad

A normal incidence tapered laser amplifier is shown to produce more than 4.5 W optical power at 810 nm in a diffraction-limited beam. A new angled-facet tapered laser amplifier has demonstrated as much as 5 W optical power in a diffraction-limited be

Optical Amplifiers and Their Applications.
Tapered semiconductor laser amplifiers have been one of the most successful approaches for producing high optical power in a diffraction limited beam [1-4]. Until now, this work has been done using anti-reflection coated normal incidence laser facets

Multimode interference (MMI) devices, based on the self-imaging effect, exhibit low excess loss, ultra-compact size, wavelength and polarization insensitivity. These desirable characteristics make MMI splitters/combiners very attractive for wavelengt
