ABSTRACTIntegrated detection of light propagating in an optical waveguide by a photodetector array fabricated directly on the waveguide surface is demonstrated. Laser recrystallization of LPCVD polysilicon patterned with periodically-spaced anti-reflection stripes is utilized. Lateral p-i-n photodiode elements formed by ion implantation are characterized by reverse leakage currents of < 10−11 amp and a typical breakdown voltage of 50 volts. Optical response is found to be linear over a dynamic range of greater than 55 dB.

The main directions in the development of the spectral systems for scintillation atomic emission analysis of powdered geological samples are aimed at increase in the sensitivity, spectral resolution, and speed of the spectrum analyzers to reduce the detection limits. The goal of the study is developing of high-speed MAÉS analyzers with hybrid assemblies of the arrays of 14 multichannel photodetectors of two types: high-sensitivity BLPP-2000 and BLPP-4000 photodetector array with high spatial resolution and theoretical estimation of the signal-to-noise ratio when recording scintillation and integral spectra with aforementioned photodetectors. The high-speed MAÉS analyzers with BLPP-2000 and BLPP-4000 photodetector arrays are designed so as to provide parallel readout of photodetectors in hybrid assemblies. They consist of 14 BLPP 2000 or BLPP 4000 photodetectors and records the spectra in the 190 – 350 nm wavelength range on a «Grand» spectrometer. The minimum exposure time is 0.9 and 1.7 msec, respectively. It is shown that in measurements of spectral-line intensities using BLPP-2000, the signal-to-noise ratio is 3 times higher in integral analysis and 5 times higher in scintillation analysis compared to measurements with BLPP-4000 photodetector array.
