Terahertz Self-Induced Dynamic Slow-Light Behavior in Metasurfaces

Soumyajyoti Mallick, Nityananda Acharyya, Vineet Gupta, Shreeya Rane, Koijam Monika Devi, Ashutosh Sharma, József Fülöp, Dibakar Roy Chowdhury

Dynamically reconfigurable metasurfaces are complex to realize because they require exotic materials, external stimuli, or both. However, with the advent of intense THz transients, these conventional preconditions can be bypassed. Strong THz fields are capable of invoking modulation of the...

19 mW/μm² and 24.5 % PAE at 94 GHz for 0.30-μm Transferred InP/GaAsSb DHBT on Si-HR

Abdelmalek Zemour, Malek Zegaoui, Yannick Roelens, Etienne Okada, Pascal Chevalier, Mohammed Zaknoune

InP HBT technology is a suitable candidate for the future 6G networks that require very high bandwidth. It has already demonstrated high-frequency operation with fmax exceeding 1 THz [1]. However, this performance comes at the cost of aggressive scaling which increases thermal resistance (Rth) due...
