High Q-factor micro-cavity laser: Fabrication and lasing emission properties

Porous Silicon Microcavities Based Photonic Barcodes

“…[ 2 ] They have been developed from several materials like silica, silicon, GaAs, etc., with many different topological approaches as spherical microcavities, [ 3 ] waveguide resonators, [ 4 ] and photonic crystal microcavities [ 5 ] among others. They have been used extensively as optical components for several applications like lasers, [ 6 ] and optical signal processing devices. [ 7 ] Among all optical resonators, spherical cavities constitute one of the most interesting approaches since their fabrication methods are relatively simple.…”
