Broadband terahertz modulators using self-gated graphene capacitors

Kakenov, N.; Balci, O.; Polat, E. O.; Altan, H.; Kocabas, C. (Optical Society of America, 2015)

We demonstrate a terahertz intensity modulator using a graphene supercapacitor which consists of two large-area graphene electrodes and an electrolyte medium. The mutual electrolyte gating between the graphene electrodes ...
Graphene-gold supercapacitor as a voltage controlled saturable absorber for femtosecond pulse generation

Baylam, I.; Balci, O.; Kakenov, N.; Kocabas, C.; Sennaroglu, A. (Optical Society of America, 2016-02)

We report, for the first time to the best of our knowledge, use of a graphene-gold supercapacitor as a voltage controlled fast saturable absorber for femtosecond pulse generation. The unique design involving only one ...
