Excitonic electroabsorption spectra in semiconductor epilayers and heterostructures have spectral structure that contributes to modulator performance in broad-band applications such as femtosecond pulse manipulation. We define several electro-optic s

The responsivity at a constant detection area of non-steady-state photoinduced electromotive force (photo-emf) detectors is improved by a factor equal to the number of contact pairs contained in asymmetric interdigitated surface contacts. The polar n

Summary form only given. Laser-based ultrasound detection uses photo-induced emf. The low responsivity of all conventional photo-emf sensors has been a serious challenge because it is more than an order of magnitude less sensitive than conventional p

We demonstrate enhanced responsivity in GaAs photo-EMF adaptive photodetectors using a novel asymmetric interdigitated electrode configuration with fine spacing. We observe enhancements even when only a fraction of an optical fringe is collected betw

An ongoing challenge for laser-based ultrasound sensors is to improve the sensitivity of adaptive photodetectors. This class of sensor is compact, robust, and simple to implement. Moreover, it can optically detect the desired ultrasound information a

We show that photo-emf detectors using asymmetric interdigital contacts have a responsivity that increases linearly with the number of electrode pairs relative to a single-pair, conventional device. We demonstrate a 32-fold enhancement using this sch

The use of interdigitated metal-semiconductor-metal contacts on semi-insulating GaAs enhances the responsivity of photoinduced-electromotive-force (photo-EMF) adaptive detectors by reducing the carrier transit time between electrical contacts. The un
