Single structure spectroscopy on a monolithic chip to be unveiled at Photonics West

Photonics West 2012:ZiNIR Ltd will unveil Solo Spectroscopy, a next generation of spectrometer based on the concept of resonator-based, diode-integrated spectrometer chip.

The Solo Spectroscopy technology offers the only spectrometer where both dispersion and detection functions are co-located within a single structure, a high-Q microdiskring resonator etched into a monolithic chip. Since photons do not need to travel between a grating (or mirror) and a detector, the opportunity for stray light is reduced. This offers huge potential for enhanced spectral properties.

The main benefit of monolithic chip-based spectrometry is its robust, go-anywhere character: it can sustain extreme temperatures and conditions, has no electrical or mechanical moving parts and has low power and footprint requirements. Multiple chips can be easily embedded into buildings, cars, clothes, electronic equipment - challenging locations where spectroscopy has not previously been deployed.

For anyone wanting to hear more about this emerging technology, Professor Stephen Sweeney will be presenting on "The development of a novel monolithic spectrometer chip concept"*, at 11.20am, Tuesday 24th January 2012, Room 236 (Mezzanine).

ZiNIR is also exhibiting in the UK Pavilion, Booth #4109, North Hall between Tuesday 24th and Thursday 26th January 2012 where applications for the diode-integrated spectrometer chip will be more fully visualised.

ZiNIR Chief Technology Officer Professor Stephen Sweeney said: "This is a radical departure from conventional spectroscopic methods. By creating a chip that directly and selectively converts light at pre-determined wavelengths we cut-out much of the complexity of conventional spectroscopy in a rugged, cheap to produce chip. This really has the potential to open spectroscopy-up in hitherto unreachable areas".
