In this work we focus our attention on the growth and development of low Miller index faces on patterned InP substrates for the InGaAs InP system. In particular, we present an extensive study about the dependence of growth rate and facet development

A high-yield 10Gb/s electroabsorption-modulated DFB laser for spans up to 10km is presented. Compared to a directly-modulated DFB laser, it offers higher dynamic performances over the whole 0÷85°C temperature range allowing simplified RF test and c

In this work we present a wavelength converter based on a Michelson interferometer. It is obtained by monolithic integration of two-semiconductor optical amplifiers with a passive waveguided X-coupler, incorporating turning mirrors. It operates in th

A precise localization of dark line defects in failed AlGaAs/GaAs laser diodes has been achieved by means of scanning optical microscope (SOM) techniques. The analytical scheme has been based on optical beam induced current (OBIC) and photoluminescen

The use of optical beam induced current (OBIC) and photoluminescence (PL) imaging is a valuable tool for failure analysis of laser diodes. Examples of applications to three different types of lasers demonstrate the effectiveness of the approach and t

An extensive investigation into the optical properties of K+-Na+ ion-exchanged waveguides in soda-lime glass over a wide range of time and temperature is described. From accurate measurements of effective indices, refractive-index profiles and birefr

A method to derive the concentration profile directly by the refractive index profile measurements was developed for binary silica glasses. Using the Lorenz-Lorentz relation, it is possible to derive the molecular electronic polarizability values at
