High-efficiency reflector-less dual-level silicon photonic grating coupler

光子学研究:英文版 2023年第7期11卷 1275-1283页

作者： VALERIO VITALI THALíA DOMíNGUEZ BUCIO COSIMO LACAVA RICCARDO MARCHETTI LORENZO MASTRONAR TEERAPAT RUTIRAWUT GLENN CHURCHILL JOAQUíN FANECA JAMES C.GATES frederic gardes PERIKLIS PETROPOULOS Optoelectronics Research Centre University of SouthamptonSouthamptonSO171BJUK Electrical Computer and Biomedical Engineering DepartmentUniversity of Pavia27100 PaviaItaly Advanced Fiber Resources Milan S.r.l. 20098 San Donato MilaneseItaly Currently at Instituto de Microelectrónica de Barcelona IMB-CNM(CSIC)Campus UAB08193 BellaterraSpain

We present the design and experimentally demonstrate a dual-level grating coupler with subdecibel efficiency for a 220 nm thick silicon photonics waveguide which was fabricated starting from a 340 nm silicon-on-insulator *** proposed device consists of two grating levels designed with two different linear apodizations,with opposite chirping signs,and whose period is varied for each scattering unit.A coupling efficiency of-0.8 d B at1550 nm is experimentally demonstrated,which represents the highest efficiency ever reported in the telecommunications C-band in a single-layer silicon grating structure without the use of any backreflector or indexmatching material between the fiber and the grating.
