We compare the characteristics of three electroabsorption modulators fabricated using GaAs/AIGaAs multiple quantum welt structures with well widths 47, 87, and 145 Ã…. We find that the narrow well structure provides the largest change in transmission. The 87 Ã… well structure provides the largest contrast ratio, while the wide well sample offers the lowest operating voltage.

    The emission wavelength of a GaInNAs quantum well (QW) laser was adjusted to 1310 nm, the zero dispersion wavelength of optical fibre, by an appropriate choice of QW composition and thickness and N concentration in the barriers. A triple QW design was employed to enable the use of a short cavity...

    We report on the enhanced electro-optic coefficient of GaInAsP three-step quantum wells (3SQW) for high power electrorefraction modulator applications. Measured electro-optic coefficient of the 3SQW is nearly three times higher than the conventional rectangular quantum well (RQW) at λ=1.55...
