Title:

Development of compact random fiber lasers with narrow linewidth and low frequency noise

Agreement Number:

Agreement Value:

$25,000.00

Agreement Date:

Mar 11, 2021 - Sep 30, 2022

Description:

The research goal for Dr. Bao's team is to explore the role of random grating in reducing the noise in random fiber lasers, especially the relative intensity noise (RIN), comparing with commonly used Rayleigh scattering in optical fibers. The RIN noise is normally contributed by the mode moping and mode competition for the limited laser gain. To reduce the number of modes, we plan to use strong reflection in random grating of a few centimeters to replace kilometer long weak Rayleigh fiber. The entire laser cavity length is shorted with longer cavity mode length, and hence smaller number of modes. This approach has proved to reduce the RIN.

Program:

Collaborative Science, Technology and Innovation Program – Ideation Fund

Program Purpose:

The Ideation Fund is intended to encourage, test and validate transformative research ideas generated by teams of NRC scientific personnel and external collaborators with complementary capabilities, acting as a demonstration phase for a continually-evolving suite of research and development (R&D) deliverables at the NRC. The fund supports exploratory research through two mechanisms: the New Beginnings Initiative and the Small Teams Initiative.

NAICS Code:
