Raman-assisted Rabi resonances in two-mode cavity QED

, 2011
The dynamics of a vibronic system in a lossy two-mode cavity is studied, with the first mode being resonant to the electronic transition and the second one being nearly resonant due to Raman transitions. We derive analytical solutions for the dynamics of

Investigation of a SPR based refractive index sensor using a single mode fiber with a large D shaped microfluidic channel [PDF]

, 2019
In this work, a highly sensitive surface plasmon resonance (SPR) sensor based on a single mode fiber (SMF) incorporating a large microfluidic channel (MFC) for refractive index (RI) sensing is designed and optimized using a full-vectorial finite element ...

Lossy mode resonance in photonic integrated circuits

Optics and Lasers in Engineering
In recent years, the promising phenomenon known as lossy mode resonance (LMR) has garnered significant attention in sensing applications. While existing literature in the field of LMR focuses on optical fiber systems and planar waveguides due to their simplicity, there is an absence of research on systems based on photonic integrated circuits (PICs ...

Magnetic Faraday rotation in lossy photonic structures

, 2009
Magnetic Faraday rotation is widely used in optics and MW. In uniform magneto-optical materials, this effect is very weak. One way to enhance it is to incorporate the magnetic material into a high-Q optical resonator.

Fundamental limits to optical response in absorptive systems [PDF]

, 2016
At visible and infrared frequencies, metals show tantalizing promise for strong subwavelength resonances, but material loss typically dampens the response.

Gas Detection Using LMR-Based Optical Fiber Sensors

Proceedings, 2018
This work presents a first approach to the utilization of Lossy Mode Resonance (LMR) based optical fiber sensors for gas detection. The optical sensor is based on a SnO2 thin-film fabricated onto the core of cladding removed multimode fibers (MMF).

Optical Fiber Humidity Sensor Based on Lossy Mode Resonances [PDF]

International Journal on Smart Sensing and Intelligent Systems, 2009
Abstract A novel optical fiber humidity sensor based on lossy mode resonances (LMR) has been developed. LMRs are supported here by a thin Indium Tin Oxide (ITO) coating fabricated onto an optical fiber core via a sol-gel dip coating. ITO coated optical fiber devices present a resonant maximum absorption peak in the infra-red region which
