Journal ArticleDOI
A compact silicon grating coupler based on hollow tapered spot-size converter
Asaduzzaman,Asaduzzaman,Masuduzzaman Bakaul,Masuduzzaman Bakaul,Efstratios Skafidas,Rezwanul Haque Khandokar,Rezwanul Haque Khandokar +6 more
TL;DR: A new compact silicon grating coupler enabling fibre-to-chip light coupling at a minimized taper length is proposed, which incorporates a hollow tapered waveguide and converts the spot-size of optical modes from micro- to nano-scales by reducing the lateral dimension.
Journal ArticleDOI
Performance Enhanced Butt Coupling for Effective Interconnection Between Fiber and Silicon Nanowire
Rezwanul Haque Khandokar,Masuduzzaman Bakaul,Asaduzzaman,Ampalavanapillai Nirmalathas,Stan Skafidas +4 more
TL;DR: In this article, a performance enhanced butt coupling structure incorporating a vertically and laterally tapered SiON polymer core on silicon (Si) to tunnel and widen propagating optical modes of adiabatic taper is proposed.
Journal ArticleDOI
Performance of Planar, Rib, and Photonic Crystal Silicon Waveguides in Tailoring Group-Velocity Dispersion and Mode Loss
TL;DR: In this paper, the performance of planar, rib, and photonic crystal Si waveguides by manipulating the dimensions of a Si core designed for single mode operation across the 1.2 to 1.6μm telecommunication bands was investigated.
Dissertation
Light coupling in dimension mismatch waveguides for silicon photonic integrated circuits
TL;DR: In this article, an ultra-subwavelength grating coupler has been developed with an engineered grating structure which exhibits high coupling efficiency and bandwidth without the need for bottom mirrors.
Journal ArticleDOI
Multiple layers of silicon–silica (Si–SiO 2 ) pair onto silicon substrate towards highly efficient, wideband silicon photonic grating coupler
Asaduzzaman,Asaduzzaman,Masuduzzaman Bakaul,Masuduzzaman Bakaul,Stan Skafidas,Rezwanul Haque Khandokar,Rezwanul Haque Khandokar +6 more
TL;DR: In this article, a single mode waveguide grating coupler based on multiple Si-SiO2 pairs onto Si substrate has been designed and a numerical analysis has been carried out to calculate optimum thickness of the layers of SiO2 that ensures the constructive interference between reflected waves and actual guided wave for high coupling efficiency.
