N'oge na-adịbeghị anya, otu ndị nyocha na Singapore enweela ọganihu dị mkpa n'ọhịa nke isi iyi ọkụ dị iche iche na mpempe akwụkwọ dị larịị. Ndị otu nyocha ahụ mepụtara mgbawa microcavity optical nwere spectrum dị larịị, sara mbara na nso ikuku mgbasa, ma kechie mgbawa optical nke ọma na njikọ ọnụ (mfu njikọ na-erughị 1 dB). Dabere na mgbawa microcavity optical, a na-emeri mmetụta thermo-optical siri ike na microcavity optical site na atụmatụ teknụzụ nke ịgbapụ okpukpu abụọ, a na-enwetakwa isi iyi ọkụ multi-wavelength nwere mmepụta spectral dị larịị.
