This Letter presents the design and experimental results for an on-chip photonic device for laser spectrum monitoring that combines a nanospectrometer and an array of Young's interferometers. The array of Young's interferometers and the spectrometer measure the width and wavelength of a spectrum in visible light, respectively. The accuracy of spectral width measurements is around 10% for FWHM higher than 2.5 pm. The spectrometer-on- chip is based on a digital planar hologram, and provides a resolution around 145 pm within the spectral range of 719-861 nm (142 nm bandwidth). The performance of the device is demonstrated for distinguishing between the single- and two-longitudinal mode operation of a fiber Bragg grating laser diode with 23 pm mode separation. © 2014 Optical Society of America.

The fabrication of digital planar holograms by Step and Repeat UV nanoimprint lithography is reported. It opens a route for commercial development of new nanophotonic devices based on digital planar holography. Two first applications to be demonstrated are the high resolution spectrometer chips and the enhancement of brightness and power of laser diodes. © 2011 OSA.

Computer-generated planar holograms are a powerful approach for designing planar lightwave circuits with unique properties. Digital planar holograms in particular can encode any optical transfer function with high customizability and is compatible with semiconductor lithography techniques and nanoimprint lithography. Here, we demonstrate that the integration of multiple holograms on a single device increases the overall spectral range of the spectrometer and offsets any performance decrement resulting from miniaturization. The validation of a high-resolution spectrometer-on-chip based on digital planar holograms shows performance comparable with that of a macrospectrometer. While maintaining the total device footprint below 2 cm2, the newly developed spectrometer achieved a spectral resolution of 0.15 nm in the red and near infrared range, over a 148 nm spectral range and 926 channels. This approach lays the groundwork for future on-chip spectroscopy and lab-on-chip sensing. © 2014 CIOMP. All rights reserved.

Digital planar holography enables the creation of a new generation of integrated photonic circuits with desired transfer function. We give here, for the first time, the basis for designing computer-generated planar holograms and demonstrate their application for spectroscopy-on-chip. Nanospectrometer chips are demonstrated with unmatched spectral resolution of up to 2 · 10 5. A specific configuration is demonstrated for easy integration of planar holograms into the full spectrometer system. The ultraminiaturization and very high performances of the devices are a breakthrough in spectroscopy and open a novel route for the digital processing of light. © 2011 IEEE.

Experimental results are presented on selection of high-order modes in broad aperture laser diode coupled with digital planar hologram (DPH). Computer-generated hologram DPH fabricated on SiO2Gex waveguide core determines the spectrum and field distribution at the laser output. The technology allows a temperature-stable spectral narrowing down to 0.6 nm and a decrease of the far-field distribution width from 6.5° to 2°. These results open a novel route for increasing the brightness and wavelength temperature stabilization of high-power laser diodes by coupling with planar photonic circuit. © 2013 Optical Society of America.

Digital planar holograms (DPH) are successfully fabricated for the first time by nanoimprint lithography (NIL). A state-of-the-art UV-NIL process is developed by combining both advantages of step and repeat technology at low pressure for high-throughput and imprinting of spin-coated resist films for easy pattern transfer. The nanofabrication process is used in order to replicate DPH structures, composed of multi-million lines grating, into silicon dioxide waveguide core. Optical performances of nanospectrometers chips are in agreement with simulations. © 2011 Elsevier B.V. All rights reserved.

A novel type of multiband wavelength demultiplexer for on-chip spectroscopy applications is proposed, and first results of the device fabrication and characterization are reported. The devices are based on computer-designed digital planar holograms, which involve millions of lines specifically located and oriented in order to direct output light into designed focal channels according to the wavelength. Devices operate in four individual bandwidths with-in the visible range (477.2-478.0 nm, 528.8-529.9 nm, 586.4-587.7 nm, 628.9-630.4 nm) with 96 channels and spectral channel spacing down to 0.0375 nm/channel. © 2012 Optical Society of America.
