Title:
VAPOR CELL STRUCTURE FOR PREVENTING METAL CONDENSATION
Document Type and Number:
WIPO Patent Application WO/2024/096158
Kind Code:
A1
Abstract:
The present invention relates to a vapor cell structure manufactured by a micro-electro mechanical systems (MEMS) process. Disclosed is a vapor cell structure comprising: a frame having at least one hollow formed through one portion thereof; substrates sealing the respective sides of the hollow; and metal nanoparticles which are disposed on one side of a substrate, overlap the hollow in the direction in which the hollow extends, and when light waves are incident within a preset wavelength range, induce surface plasmon resonance by light waves of the same wavelength in order to detect the atomic energy level. Accordingly, a temperature deviation depending on the location of the vapor cell structure is further alleviated, the phenomenon of metal condensation on the path of the light waves can be prevented, and the transmittance of light waves incident on the vapor cell structure can be further improved.
