Abstract
A spectroscopy system is described. The spectroscopy system includes a cell, a photodiode, and mirrors. The cell has walls forming a chamber therein. The chamber is configured to receive laser signal(s) and retaining a vapor therein. The vapor fluoresces in response to the laser signal(s). The mirrors are configured to direct fluorescent light from the vapor toward the photodiode. In some embodiments, the spectroscopy system is incorporated with a photonic integrated circuit.
Claims17
A spectroscopy system, comprising:
- a cell having one or more walls and forming a chamber therein, the chamber being configured to receive at least one laser signal and retaining a vapor therein, the vapor fluorescing in response to the at least one laser signal, wherein at least a portion of a first wall of the one or more walls is at least partially transparent to fluorescent light from the vapor;
- a photodetector;
- and
- a plurality of mirrors;
- wherein:
- at least one mirror of the plurality of mirrors is internal to the chamber and is oriented to redirect at least some of the fluorescent light toward the photodetector such that redirected fluorescent light passes through the portion of the first wall before reaching the photodetector, and/or
- at least one mirror of the plurality of mirrors is external to the chamber and is oriented to redirect at least some of the fluorescent light toward the photodetector after the at least some of the fluorescent light passes through the portion of the first wall.

A method for providing a spectroscopy system, comprising:
- providing a cell having one or more walls and forming a chamber therein, the chamber being configured to receive at least one laser signal and to retain a vapor therein, the vapor fluorescing in response to the at least one laser signal, wherein at least a portion of a first wall of the one or more walls is at least partially transparent to fluorescent light from the vapor;
- providing a photodetector;
- and
- coupling a plurality of mirrors to the one or more walls, wherein:
- at least one mirror of the plurality of mirrors is internal to the chamber and is oriented to redirect at least some of the fluorescent light toward the photodetector such that redirected fluorescent light passes through the portion of the first wall before reaching the photodetector, and/or
- at least one mirror of the plurality of mirrors is external to the chamber and is oriented to redirect at least some of the fluorescent light toward the photodetector after the at least some of the fluorescent light passes through the portion of the first wall.
