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 elu ike mmepụta, ma ya mmepụta ntụpọ bụ elliptical, n'ikuku àgwà adịghị mma, na osisi udi kwesịrị gbanwee na a usoro.
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 mpaghara na-arụsi ọrụ ike iji meziwanye mgbasa ọkụ, na-amụba ebe a na-emepụta ìhè iji belata njupụta ngwa anya nke ọkụ ahụ iji zere mmebi anya, ike mmepụta nke ihe ruru ọtụtụ narị milliwatts nwere ike nweta na otu transverse mode waveguide Ọdịdị.
Maka 100mm waveguide, otu akụkụ-emitting laser nwere ike nweta ọtụtụ iri watts nke mmepụta ike, ma n'oge a, waveguide bụ nnọọ multi-mode na ụgbọ elu nke mgbawa, na mmepụta beam akụkụ ruru erukwa 100: 1, na-achọ a mgbagwoju osisi nhazi usoro.
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 bụ oke oke. Iji meziwanye ike mmepụta nke ukwuu, teknụzụ n'usoro na-abata. The technology integrates multiple Laser nkeji 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 mwepu technology na-eji ikewapụ ọ bụla ìhè emitting unit na n'usoro, nke mere na ha adịghị egbochi ọ bụla ọzọ, na-akpụ a multi-aperture lasing, ị nwere ike dịkwuo mgbawa na-amụba ike unit nke Integrated ọnụ ọgụgụ. Ihe mgbawa laser semiconductor a bụ mgbawa laser array (LDA), nke a makwaara dị ka mmanya laser semiconductor.
