Abstract

Optical multiplexers/demultiplexers developed for the telecommunication industry, at the level of the basic principles, perform essentially the same functions as general-use optical spectrometers. The spectrometer design inspired by the telecom devices would represent an extremely compact device compatible with the manufacturing procedures in integrated optoelectronics and micro-optics. In this paper we summarize our recent results on development of a miniature optical spectrometer. The spectrometer uses a diffractive optical element integrated with a planar optical waveguide. It is designed to provide spectral resolution of at least 2nm in the entire visible spectral range from 400nm- 700nm, and simultaneously resolve spectra from up to 35 independent optical inputs. The optical part of the spectrometer fits volume below 10mm³. The spectrometer is designed for on-chip diagnostic systems, in particular for fluorescence detection of hazardous materials. A device prototype with diffractive optical element fabricated using electron beam lithography is manufactured and tested.
