Low-Loss Slow Light inside High Contrast Grating Waveguide
نویسندگان
چکیده
We propose a novel hollow-core slow light waveguide using high contrast grating (HCG). Light propagates in air along a path bounded by two HCG layers. A strong interaction between the light and the HCG leads to a large group index, and thus the slow light effect. Waveguide loss and group index can be optimized separately by tuning the HCG and waveguide parameters. High performance slow light is obtained with <0.1 dB/cm loss, >120 group index and >120 GHz bandwidth.

Dispersion properties of high-contrast grating hollow-core waveguides.
We present unique dispersion characteristics of high-contrast grating (HCG) hollow-core waveguides and show that slow light can be facilitated using internal resonances developing inside the waveguide walls. In addition, we show a fast and precise method of inferring the dispersion information from the waveguide angular reflectivity spectrum.
متن کاملFundamental limits to slow-light arrayed-waveguide-grating spectrometers.
We present an analytical model that describes the limiting spectral performance of arrayed-waveguide-grating (AWG) spectrometers that incorporate slow-light methods. We show that the loss-limited spectral resolution of a slow-light grating-based spectrometer scales as the loss-group-index ratio of the waveguide array. We further show that one can achieve a spectral resolution of a few GHz using...
متن کاملDesign of Arrayed Waveguide Grating based Optical Switch for High Speed Optical Networks
This paper demonstrates the design of an Arrayed Waveguide Gratings (AWG) based optical switch. In the design both physical and network layer analysis is performed. The physical layer power and noise analysis is done to obtain Bit Error Rate (BER). This has been found that at the higher bit rates, BER is not affected with number of buffer modules. Network layer analysis is done to obtain perfor...
متن کاملLight modulation with electro-optic polymer-based resonant grating waveguide structures.
A novel modulator design incorporating an E-O polymer into a resonant grating waveguide structure is presented. Using purely polymeric material we developed a resonant grating waveguide structure having low loss and high finesse, with approximately 2nm spectral line width at 1.55 mum. An externally applied voltage modulates the refractive index of the E-O waveguide, thereby shifting the resonan...
متن کاملDesign and analysis of transmission enhanced multi-segment grating in MZI configuration for slow light applications.
This paper proposes to use slow light effects near the Brillouin zone band edge of one-dimensional gratings for reducing the size of integrated electro-optic (EO) modulators. The gratings are built within the arms of a Mach-Zehnder Interferometer (MZI) for intensity modulation. To overcome the inherent high reflection and low extinction ratio, we introduce various multi-segment grating designs....
