C-band 160 Gbs-1 Zero-bias Graphene Photodetectors: Breaking the Responsivity-Bandwidth Trade-off by Heterostructure Engineering
Karuppasamy Pandian Soundarapandian, Alberto Montanaro, Ioannis Vangelidis +17
Graphene photodetectors offer ultrafast response and broadband operation, but their responsivity is typically limited by rapid hot-carrier cooling, leading to a trade-off between s…
Single-mode emission by phase-delayed coupling between nano-lasers
T. V. Raziman, Anna Fischer, Riccardo Nori +10
Near-field coupling between nanolasers enables collective high-power lasing but leads to complex spectral reshaping and multimode operation, limiting the emission brightness, spati…
Mode visualisation and control of complex lasers using neural networks
Wai Kit Ng, T. V. Raziman, Dhruv Saxena +7
Understanding the behaviour of complex laser systems is an outstanding challenge, especially in the presence of nonlinear interactions between modes. Hidden features, such as the g…
A silicon photonics waveguide-coupled colloidal quantum dot photodiode sensitive beyond 1.6 um
Chao Pang, Yu-Hao Deng, Ezat Kheradmand +6
Silicon photonics faces a persistent challenge in extending photodetection capabilities beyond the 1.6 um wavelength range, primarily due to the lack of appropriate epitaxial mater…
