Electrically Controllable Saturable Absorption in Hybrid Graphene-Silicon Waveguides

Abstract: Electrical tunability of saturable absorption is demonstrated in a graphene/SOI hybrid waveguide. The saturation modulation depth is tunable between 0 and 2.2 dB (∼0-40% decrease of absorption at saturation), with saturation powers between ∼1.25-2.5 W.

“…Recently, it is reported that the evanescent field absorption may guarantee the maximum efficiency of the nonlinear effect of the layered materials in the fiber1920. And the evanescent field absorption of graphene can be conveniently tuned by the electrical signals in the fiber laser system1213. According to reports about the evanescent field absorption in the fiber laser, we believe the electrical controlled laser can also be obtained based on the waveguide, via the controllable evanescent field absorption.…”

“…And, graphene can be used as an efficient saturable absorber (SA) in a laser system for the generation of ultrafast lasers4567. Another fascinating feature is that the Fermi level of a graphene layer can be tuned by electrical signals48910111213. A shift in the Fermi level will change the optical absorption of graphene, allowing the electrical control of the optical property of graphene.…”

“…Είναι, μάλιστα, το πρώτο μη γραμμικό φαινόμενο που παρατηρήθηκε πειραματικά στο γραφένιο, μέσω της μελέτης παλμικών πηγών οπτικών ινών (pulsed fiber lasers) [82,83]. Στο κομμάτι των ολοκληρωμένων φωτονικών κυκλωμάτων, μόλις πρόσφατα το εν λόγω φαινόμενο άρχισε να απασχολεί την κοινότητα, με τις πρώτες εργασίες να δίνουν επίσης ενθαρρυντικά αποτελέσματα για τη συνέχεια της ερευνητικής δραστηριότητας [84,85].…”
