THz Ultrastrong Coupling in an Engineered Fabry–Perot Cavity [PDF]

ACS Photonics, 2021
We report a monolithic THz planar Fabry-Perot cavity fabricated with wafer bonding and provided with metallic mirrors with subwavelength apertures. We demonstrate its coupling to the cyclotron resonance of a high-mobility, two-dimensional electron gas. Q factors up to 89 are observed for the first mode at similar or equal to 300 GHz, with cooperativity

Photon/spin echo in a Fabry–Perot cavity

Optics Letters, 2022
The pulse area theorem is a well-known versatile analytical tool for capturing the general nonlinear nature of light propagation in a two-level medium. Here we derive the pulse area theorem for the photon/spin echo signal generated in a one-side cavity.

Performance of a dual Fabry–Perot cavity refractometer

Optics Letters, 2015
We have built and characterized a refractometer that utilizes two Fabry-Perot cavities formed on a dimensionally stable spacer. In the typical mode of operation, one cavity is held at vacuum, and the other cavity is filled with nitrogen gas. The differential change in length between the cavities is measured as the difference in frequency between two ...

Fabry–Perot cavities made easy

2023
The theoretical investigations on the dynamics and the instabilities in nonlinear optical systems have considered almost exclusively ring cavities, because the field propagation is unidirectional, whereas in Fabry–Perot cavities there are two field envelopes propagating in opposite directions, which constitutes a much more complex context.

Temperature-compensated cryogenic Fabry–Perot cavity

Applied Optics, 1997
We show that temperature compensation based on differential thermal expansion between sapphire and fused silica can be used to create a Fabry-Perot cavity with an exceptionally low coefficient of thermal expansion at low temperatures. We describe the design of such a cavity that utilizes shaped fused silica mirrors and a sapphire spacer.
