Trosolwyg
Rwy'n Gydymaith Ymchwil mewn Optoelectroneg yn yr Ysgol Ffiseg a Seryddiaeth, Prifysgol Caerdydd. Mae fy ngweithgareddau ymchwil yn rhan o Hwb Gweithgynhyrchu Lled-ddargludyddion Cyfansawdd y Dyfodol (CS Hub), QUantum Dot On Silicon (QUDOS), a phrosiectau CSconnected Cronfa Cryfder mewn Lleoedd (SiPf).
O dan y Ganolfan CS, mae fy ngwaith yn canolbwyntio ar gynhyrchu a nodweddu dyfeisiau optoelectroneg III-V ar raddfa, yn enwedig VCSELs, LEDs ac EELs. Ar gyfer QUDOS, rwy'n gweithio ar ddatblygu cydrannau QD ar gyfer cylchedau integredig ffotonig. O dan SiPf, fy ffocws ar weithgynhyrchu wafer ar raddfa fawr Gaas a thechnolegau cyfathrebu a synhwyro optegol y genhedlaeth nesaf.
