Advanced spectroscopy system for micro- and nanolaser measurement and characterization
Abstract
Publicly Releasable The laser has become an indispensable tool in our society since its inception in 1960. High-quality lasers with, exceptional properties, such as low threshold, high efficiency, high-output power, high speed, small size, and single-mode operatio,n, have, therefore, become essential for numerous critical applications. Recently, micro- and nanolasers can generate coherent light, at much smaller scales. Over the past decade, researchers have shown intense interest in small lasers, which are more compact, fast,er, and more energy-efficient than larger conventional lasers. These exceptional capabilities make small lasers attractive for vario,us critical applications, such as optical interconnects, optical sensing, and far-field optical mode synthesis. Among the many types, of lasers, the photonic crystal laser is one of the most prominent due to its exceptional spontaneous emission control and dispersi,on engineering flexibility. However, photonic crystal lasers are sensitive to fabrication imperfections and typically have a large f,ootprint and high energy consumption due to their multimode nature. We propose developing robust topologically-protected merging bou,nd states in the continuum (BIC) photonic crystal microlasers with an ultracompact footprint and low energy consumption for forging, photonic crystal lasers into a more robust system. Funding is requested for equipment to upgrade our existing system to a more adva,nced spectroscopy system in the PIs laboratory at the University of Nebraska-Lincoln (UNL) for micro- and nanolaser measurements an,d characterizations. Specifically, we will acquire a high-efficiency photon detection and timing electronics subsystem to perform bo,th photon correlation measurements and photoluminescence lifetime measurements. We also propose purchasing a spectrometer subsystem, with a higher spectra resolution that will substantially extend the current linewidth measurement limit in the PI s lab by one orde,r of magnitude. The DURIP will provide essential equipment for postdoc scholars and graduate and undergraduate students at UNL to pe,rform research within the DoD s interest. Our work will be beneficial for a number of ONR funded research projects at UNL. The PI is, ready to engage in multiple collaborations and willing to make the new facilities available to researchers in these labs, thereby e,nhancing UNLs research infrastructure and capability.
