Confocal Fluorescence Microscopy

Confocal Fluorescence Microscopy

Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

Area of Science:

Optics and Photonics
Semiconductor Lasers

Background:

Angled-grating broad-area lasers are key for high-power, high-brightness diode sources.
These lasers utilize angled gratings to support zigzag lasing modes and suppress Fabry-Perot feedback.

Purpose of the Study:

To propose and demonstrate a folded cavity design for angled-grating broad-area lasers.
To reduce the physical footprint of long-cavity, high-power lasers.

Main Methods:

Leveraging the mirror symmetry of the zigzag lasing mode.
Implementing a folded cavity architecture in angled-grating broad-area lasers.

Main Results:

The folded cavity design successfully reduces the required wafer space.
The laser demonstrated good far-field beam quality.
A slight increase in threshold current and a decrease in slope efficiency were observed due to additional interface loss.

Conclusions:

Folded cavity angled-grating broad-area lasers provide a space-saving solution for high-power diode laser applications.
The design offers a trade-off between reduced footprint and optical efficiency.
