“…It has been shown recently that slow light can also be used to enhance the spectral performance of various types of interferometers [14][15][16][17]. The ability to increase the spectral resolution of interferometric spectrometers by a factor as large as the group index can have many important implications for modern optical technology.…”

We investigate how the use of slow-light methods can enhance the performance of various types of spectroscopic interferometers under practical conditions. We show that, while in ideal cases the enhancement of the spectral resolution is equal to the magnitude of the group index of the slow-light medium, the ratio between the associated gain or loss and the group index of the slow-light medium actually determines the spectral resolution under more-general conditions. Moreover, the dispersion of this ratio leads to frequency-dependent spectral resolution, which limits the useful working bandwidth of the interferometer. We also evaluate the performance of interferometers using three specific slow-light processes in terms of the achievable spectral resolution and the effective working finesse. We show that the spectral resolution is typically limited by the characteristic linewidth of each slow-light process and that there is no fundamental upper limit for the effective working finesse.

“…8 A number of schemes have been proposed to enhance the performance of interferometers, such as using PhC structures to minimize the size of on-chip devices 9 and electromagnetically induced transparency to increase the rotation sensitivity of a Sagnac interferometer. 10 In the present paper, we propose a novel design of spectroscopic interferometers using slow-light media. We demonstrate experimentally that the spectral sensitivity of an interferometer is proportional to the group index n g , which can be as large as 10 7 under appropriate conditions.…”

Public reporting burden for the collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. We demonstrate experimentally that the spectral sensitivity of an interferometer can be greatly enhanced by introducing a slow-light medium into it. The experimental results agree very well with theoretical predictions that the enhancement factor of the spectral sensitivity is equal to the group index n g of the slow-light medium.

“…[10][11][12] It has recently been shown that slow light can be used to enhance the performance of various types of spectroscopic interferometers. [13][14][15][16] In particular, it has been demonstrated that, by changing the width of channel waveguides that form the array of dispersive elements in an AWG spectrometer, one can enhance the group index and hence the spectral resolution of the AWG spectrometer. 5 In this paper, we explore the use of dispersive elements based on slow light to build on-chip miniaturized AWG spectrometers with very high spectral resolution.…”

We discuss the design and development of a slow-light spectrometer on a chip with the particular example of an arrayed waveguide grating based spectrometer. We investigate designs for slow-light elements based on photonic crystal waveguides and grating structures. The designs will be fabricated using electron-beam lithography and UV photolithography on a silicon-on-insulator platform. We optimize the geometry of these structures by numerical simulations to achieve a uniform and large group index over the largest possible wavelength range.
