Mode switching in photonic crystal surface emitting lasers with back reflectors and holes of varying depths (2025)
Journal Article
Lang, B., Sewell, P. D., Vukovic, A., Boylan, K., Rihani, S., Moodie, D., Spalding, R., Hattasan, N., & Berry, G. (2025). Mode switching in photonic crystal surface emitting lasers with back reflectors and holes of varying depths. Optics Express, 33(17), 35257-35269. https://doi.org/10.1364/OE.568336

Recent advancements in photonic crystal surface emitting lasers (PCSELs) have incorporated a reflector at the back of the laser to capture light that would otherwise be lost. However, this addition introduces what we believe to be a new interference...

Assessment and Extension of Rapid Design Tools for Modelling Photonic Crystal Surface Emitting Lasers. Journal of the Optical Society of America B, 42(5), 1123-1130. https://doi.org/10.1364/josab.550022

Rapid design tools are invaluable for the fast exploration of design space and optimization of photonic crystal surface-emitting lasers (PCSELs). This paper introduces an improved extension to the fast effective index type approach and compares it ag...

Photonic circuit of arbitrary non-unitary systems (2025)
Journal Article
Talib, H., Sewell, P. D., Vukovic, A., & Phang, S. (2025). Photonic circuit of arbitrary non-unitary systems. Optical and Quantum Electronics, 57, Article 99. https://doi.org/10.1007/s11082-024-07957-5

A design framework to implement non-unitary input–output operations to a practical unitary photonic integrated circuit is described. This is achieved by utilising the cosine-sine decomposition to recover the unitarity of the original operation. The r... Read More about Photonic circuit of arbitrary non-unitary systems.
