Okwu Mmalite nke Edge Emitting Laser (EEL)

Okwu Mmalite nke Edge Emitting Laser (EEL)
Iji nweta mmepụta laser semiconductor dị elu, teknụzụ dị ugbu a bụ iji nhazi ikuku ikuku. The resonator nke onu-emitting semiconductor laser mejupụtara eke dissociation elu nke semiconductor kristal, na mmepụta doo na-emitted si n'ihu njedebe nke laser.The nsọtụ-emission ụdị semiconductor laser nwere ike nweta nnukwu ike mmepụta, ma ya. Ebe mmepụta bụ elliptical, ogo ọkụ adịghị mma, na ọ dị mkpa ka e jiri usoro nhazi osisi gbanwee ya.
Eserese na-esonụ na-egosi nhazi nke laser semiconductor na-eku ume. Oghere anya nke EEL dị n'elu nke mgbawa semiconductor ma na-ebunye laser na nsọtụ nke mgbawa semiconductor, nke nwere ike ịghọta mmepụta laser na ike dị elu, nnukwu ọsọ na obere mkpọtụ. Otú ọ dị, mmepụta ọkụ laser site na EEL n'ozuzu nwere akụkụ cross-symmetric beam cross na nnukwu angular divergence, na njikọ njikọ na eriri ma ọ bụ ihe ndị ọzọ ngwa anya dị ala.

Mmụba nke ike mmepụta EEL na-ejedebe site na nchịkọta okpomọkụ mkpofu na mpaghara na-arụ ọrụ na mmebi anya na elu semiconductor. Site n'ịbawanye mpaghara waveguide iji belata mkpokọta ikpo ọkụ na-ekpo ọkụ na mpaghara na-arụsi ọrụ ike iji meziwanye ọkụ ọkụ, na-amụba ebe a na-emepụta ìhè iji belata njupụta ike anya nke ọkụ ahụ iji zere mmebi anya, ike mmepụta ihe ruru ọtụtụ narị milliwatts nwere ike. a ga-enweta na otu transverse mode ụkpụrụ waveguide.
Maka 100mm waveguide, otu n'ọnụ-emitting laser nwere ike nweta iri puku kwuru iri nke ike mmepụta, ma n'oge a waveguide bụ ukwuu multi-mode na ụgbọ elu nke mgbawa, na mmepụta beam akụkụ ruru erukwa 100: 1, na-achọ usoro nhazi osisi siri ike.
N'echiche na ọnweghị ọganihu ọhụrụ na teknụzụ ihe onwunwe na teknụzụ uto epitaxial, ụzọ kachasị mma isi meziwanye ike mmepụta nke otu mgbawa laser semiconductor bụ ịbawanye obosara nke mgbawa nke mpaghara ọkụ. Otú ọ dị, ịba ụba nke warara obosara nke ukwuu dị mfe na-emepụta transverse elu-iji mode oscillation na filamentlike oscillation, nke ga-ukwuu belata uniformity nke ìhè mmepụta, na mmepụta ike adịghị abawanye proportionally na warara obosara, otú mmepụta ike nke. otu mgbawa nwere oke oke. Iji meziwanye ike mmepụta nke ukwuu, teknụzụ n'usoro na-abata. The technology integrates multiple laser units na otu mkpụrụ, nke mere na onye ọ bụla ìhè emitting unit na-ahịrị dị ka otu akụkụ n'usoro n'usoro na ngwa ngwa axis direction, ọ bụrụhaala na ngwa anya ikewa technology na-ekewapụ ọ bụla ìhè emitting unit n'usoro n'usoro. , nke mere na ha adịghị egbochi ọ bụla ọzọ, na-akpụ a multi-aperture lasing, ị nwere ike dịkwuo mmepụta ike nke dum mgbawa site na-amụba ọnụ ọgụgụ nke integrated ìhè emitting nkeji. Ihe mgbawa laser nke semiconductor bụ mgbawa laser array (LDA), nke a makwaara dị ka ogwe laser semiconductor.
