Grabarnik, S. (author), Emadi, A. (author), Wu, H. (author), De Graaf, G. (author), Wolffenbuttel, R.F. (author)A concept for a highly miniaturized spectrometer featuring a two-component design is presented. The first component is a planar chip that integrates an input slit and aberration-correcting diffraction grating with an image sensor and is fabricated using microelectromechanical systems (MEMS) technologies. Due to the fabrication in a simple MEMS...journal article 2008

Grabarnik, S. (author), Emadi, A. (author), Wu, H. (author), De Graaf, G. (author), Wolffenbuttel, R.F. (author)This paper reports on the development and validation of a new technology for the fabrication of variable line-spacing non-planar diffraction gratings to be used in compact spectrometers. The technique is based on the standard lithographic process commonly used for pattern transfer onto a flat substrate. The essence of the technology presented...conference paper 2008
