Compact, Single-Mode THz QCLs Get Boost from BICs
SINGAPORE, June 27, 2023 — A team at Nanyang Technological University (NTU) developed an electrically pumped, topological, bulk quantum cascade laser (QCL) that operates in the terahertz (THz) frequency range. The THz QCL is governed by a mechanism known as bound states in the continuum (BICs). BICs are waves that remain localized even though they coexist with a continuous spectrum of radiating waves that can carry energy away. BICs can confine light with a theoretically infinite Q factor, which can improve light-matter
