The optical absorption coefficient of graphene will change after injecting carriers. Based on this principle, a high-speed double-layer graphene electro-optic modulator with a ring resonator structure was designed in this paper. From the numerical simulations, we designed a modulator. Its optical bandwidth is larger than 130 GHz, the switching energy is 0.358 fJ per bit, and the driven voltage Organic Electro-Optics | Jen Research Group Organic Electro-Optics Introduction. The Jen group’s goal in the research of organic electro-optics is to advance the science and engineering of organic second-order nonlinear optical materials and their hybrid systems, enabling the development of “transformative” electro-optic (EO) technologies for ultrafast information processing. Enhanced temperature sensing with liquid-crystal filling A fast-response optical sensor based on a slot-waveguide micro-ring resonator with liquid-crystal filling enables more accurate temperature measurement with a nearly fivefold increase in sensitivity. 2 December 2013, SPIE Newsroom.

SearchMay 21, 2016 - 27 min - Uploaded by andrew mcneilMy first attempt at building the waveguide slot hopefully the first of many as I have a few ideas .. Optical ring resonators - Wikipedia To understand how optical ring resonators work, we must first understand the optical path length difference (OPD) of a ring resonator. This is given as follows for a single-ring ring resonator: = where r is the radius of the ring resonator and is the effective index of refraction of the waveguide material. Due to the total internal reflection requirement, must be greater than the index of refraction of the surrounding fluid in which the resonator is placed (e.g. air). For resonance to take ...

Compact silicon photonic waveguide modulator based on the ... induced optical modulation of a confined waveguide mode in excess of 6.5 dB at λ = 1550 nm, with 2 dB insertion loss. A 16-fold increase in VO 2 absorption across the phase transition allows the modulator to function as an effective single-pass device that is compact and broadband, in contrast to MZI and resonator-based designs. A comparison of optical modulator structures using a ... slot waveguide in the cavity region with a 100×250nm polymer region and 250×250nm silicon ridges on each side.
