Abstract
Systems and methods according to present principles provide, at room temperature, a bound state in the continuum laser that harnesses optical modes residing in the radiation continuum but nonetheless may possess arbitrarily high quality factors. These counterintuitive cavities are based on resonantly trapped symmetry-compatible modes that destructively interfere. Such systems and methods may be applied towards coherent sources with intriguing topological properties for optical trapping, biological imaging, and quantum communication.
Claims21
A single-mode bound state in the continuum laser, comprising:
- a pump source of light, the pump source of light configured to direct light into a resonant cavity, the resonant cavity configured to enable a bound state in the continuum, wherein the single-mode bound state in the continuum is configured to enable resonantly trapped symmetry-compatible modes that destructively interfere, wherein the resonant cavity is made from a material that also serves as an active gain medium of the single-mode bound state in the continuum laser.
A method of making a single-mode bound state in the continuum laser, comprising:
- a. providing a substrate;
- b. fabricating a device layer on the substrate, the device layer to be formed into multiple quantum wells;
- and
- c. fabricating a top barrier layer on the device layer,
- wherein at least the device layer comprises a laser cavity, the laser cavity configured to enable a single-mode bound state in the continuum, wherein the bound state in the continuum is configured to enable resonantly trapped symmetry-compatible modes that destructively interfere, wherein the laser cavity is made from a material that also serves as an active gain medium of the single-mode bound state in the continuum laser.
