Laser Architectures Using Quantum Well Intermixing Techniques - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240113508 titled 'Laser Architectures Using Quantum Well Intermixing Techniques

Simplified Explanation

The abstract describes a patent application for a laser chip with multiple stripes that can emit light across a wide range of wavelengths by shifting the optical gain profile of each stripe using an intermixing process.

Laser chip with multiple stripes:

 * The laser chip includes a plurality of stripes that can emit light with different ranges of wavelengths.
 * Each stripe can have its optical gain profile shifted relative to another stripe, allowing for a wide range of emitted wavelengths.

Intermixing process:

 * The optical gain profile of each laser stripe can be shifted using an intermixing process.
 * Different regions of a given laser stripe can have different intermixing amounts, further expanding the range of emitted wavelengths.

Same epitaxial wafer:

 * Multiple laser stripes can be formed on the same laser chip from the same epitaxial wafer, reducing manufacturing complexity and costs.

Different regions of a given laser stripe having different intermixing amounts:

 * This allows for precise control over the emitted wavelengths of each stripe, enabling customization for specific applications.

Original Abstract Submitted

a laser chip including a plurality of stripes is disclosed, where a laser stripe can be grown with an initial optical gain profile, and its optical gain profile can be shifted by using an intermixing process. in this manner, multiple laser stripes can be formed on the same laser chip from the same epitaxial wafer, where at least one laser stripe can have an optical gain profile shifted relative to another laser stripe. for example, each laser stripe can have a shifted optical gain profile relative to its neighboring laser stripe, thereby each laser stripe can emit light with a different range of wavelengths. the laser chip can emit light across a wide range of wavelengths. examples of the disclosure further includes different regions of a given laser stripe having different intermixing amounts.
