Threshold Characteristics of Slow-Light Photonic Crystal Lasers
Weiqi Xue, Yi Yu, Luisa Ottaviano +4
The threshold properties of photonic crystal quantum dot lasers operating in the slow-light regime are investigated experimentally and theoretically. Measurements show that, in con…
Impact of slow-light enhancement on optical propagation in active semiconductor photonic crystal waveguides
Yaohui Chen, Jakob Rosenkrantz de Lasson, Niels Gregersen +1
We derive and validate a set of coupled Bloch wave equations for analyzing the reflection and transmission properties of active semiconductor photonic crystal waveguides. In such d…
Nonreciprocal transmission in a photonic-crystal Fano structure enabled by symmetry breaking
Yi Yu, Yaohui Chen, Hao Hu +3
Nanostructures that feature nonreciprocal light transmission are highly desirable building blocks for realizing photonic integrated circuits. Here, a simple and ultra-compact photo…
Slow-light enhanced gain in active photonic crystal waveguides
Sara Ek, Per Lunnemann, Yaohui Chen +3
Slow light is a fascinating physical effect, raising fundamental questions related to our understanding of light-matter interactions as well as offering new possibilities for photo…
Fano resonance control in a photonic crystal structure and its application to ultrafast switching
Yi Yu, Mikkel Heuck, Hao Hu +6
Fano resonances appear in quantum mechanical as well as classical systems as a result of the interference between two paths: one involving a discrete resonance and the other a cont…
