Design, fabrication, and characterization of Electrically Pumped Coaxial Nanoscale Lasers - Topic 4.2
Abstract
The objective of he proposed work is to design and develop electrically pumped coaxial nanolasers capable of being modulated at several hundreds of GHz to as high as a few THz. Evidently, in addition to the electromagnetic consideration, such cavity designs need to take into account electrical, thermal, and quantum effects arising from small dimensions. For the successful fabrication of such devices, the PI will explore new techniques for material deposition. Laser characterization will include second order coherence measurement as well as typical electroluminescence measurements. A second objective (years 2 and 3) will be to investigate the efficient capture and redirecting of the emission from the coaxial nanolaser into dielectric waveguides that will be necessary in future photonic integrated systems. The main efforts will be directed towards development of coaxial nano lasers on an InP platform due to its application as the backbone of fiber optic as well as on-chip optical communication systems. The InP based MQW gain wafer will be purchased from the company OEpic, which has the capabilities to grow epitaxial layers on InP using a MOCVD technique and have been the supplier for the PIs previous work. The processing, fabrication, and characterization will be performed at the CREOL nanofabrication facility and the Material Characterization Facility (MCF) at UCF as well as the PIs labs. The PIs labs are equipped to characterize the fabricated integrated devices. The proposed work is based on the PIs previous projects and upon the successful demonstration will be the basis for their future work on characterizing the high speed response of electrically pumped coaxial nano lasers. The individual tasks which are described in detail in the proposal are as follows: 1. Design of electrically injected nano lasers 2. Fabrication of electrically injected nano lasers 3. Thermal characterization of nano lasers 4. Electrical injection testing of lasers 5. Design optimization (repeat of 1-4 above with refined designs) 6. Optical characterization of modulation bandwidth 7. Coupling of the output power through SPP waveguide 8. Rate equation modeling of nanolasers for understanding of high-speed performance 9. GaAs based nanolasers (in addition to prior InP nanolaser work)
