STGLO PHOTONIC MICROCELL™

Photonic Micro-Cell (PMC)™ technology is based on Hollow-Core Photonic Crystal Fiber (HC-PCF) and the process of filling the fiber with a chosen gas to offer photonic functionalities such as (i) Optical frequency conversion, (ii) Ultra-high power pulsed laser delivery (iii) Laser pulse compression or (iv) Frequency standards.

A PMC is a stand-alone and modular component that consists of a HC-PCF filled with gas and fiber terminations. The presence of gas within an optical fibre on a micron scale provides a million-fold increase in the gas-laser efficiency compared to traditional lasing methods and opens up the unique ability for functionalization. For example, with a Raman gas one can produce new wavelengths and hence create new applications. There are different variants of HC-PCF used within the PMC family of components. The Inhibited-Coupling guiding HC-PCF such as Kagome fiber produces particularly good results with a high damage threshold and a very wide bandwidth.

The PMC comes in different forms tailored to either the applications or the laser power requirements or to specific housing requirements. Below is a list of the different PMC forms we can deliver.
