Ingabe kusezivivinyweni eziqondile lapho umuntu ephishekela khona ngokulangazela lokho kuzinza kokukhanya okuphelele? Siyazi kahle ukuthi...Funda kabanzi -
Yethula isisombululo esisha se-RF phezu kwe-fiber Link esingu-40GHz
Yethula isisombululo esisha se-40GHz RF over fiber Link Emkhakheni wokuxhumana nge-microwave, isisombululo sendabuko se-RF over fiber Link besilokhu sivinjelwa yizinkinga ezimbili ezinkulu: Izintambo ze-coaxial ezibizayo kanye nama-waveguides awakhulisi nje kuphela izindleko zokuthunyelwa, kodwa futhi akhuphula ngokuqinile...Funda kabanzi -
Yethula uhlelo lwe-optical lokukhishwa kwe-laser kanye nokwamukelwa kwayo
Yethula uhlelo lwe-optical lokukhishwa nokwamukelwa kwe-laser Uhlelo lwe-optical lokukhishwa nokwamukelwa kwe-laser luqukethe izingxenye ezimbili ezinkulu: i-optical module yokukhishwa kanye ne-reception optical module. Amasimu ayo asetshenziswa kakhulu yizinhlelo zokucubungula i-laser, uhlelo lokuthola i-fluorescence...Funda kabanzi -
Yiziphi izici ezithinta ubude be-wavelength ye-laser?
Yiziphi izici ezithinta ubude be-laser? Ububanzi be-laser abunqunywa yisici esisodwa, kodwa bunqunywa ngokubambisana yindlela esebenza ngayo ngokomzimba (imisebe evuselelwe) kanye nomklamo othile wesakhiwo. Ubukhulu be-core buncike esakhiweni samandla sento esebenzayo...Funda kabanzi -
Uhlobo olusha lwe-photodetector luthola izimpawu zokukhanya ezibuthakathaka ebhendini engu-2μm
Uhlobo olusha lwe-photodetector luthola izimpawu zokukhanya ezibuthakathaka ebhendini le-2μm Emikhakheni eminingi yanamuhla yocwaningo lwesayensi kanye nezicelo zezimboni, ukubanjwa nokuhlaziywa okunembile kwezibonakaliso zokukhanya ezibuthakathaka bekulokhu kuyisihluthulelo sokushayela ubuchwepheshe obusha. Ikakhulukazi ku-2-...Funda kabanzi -
Izici eziyinhloko zama-laser
Izici eziyinhloko zama-laser Ukukhiqizwa kwama-laser Umbono "wokukhanya okuzenzakalelayo nokushukunyiswayo" owaphakanyiswa ngu-Einstein ngo-1916 uyisisekelo esibonakalayo sohlelo lwe-laser lwanamuhla. Ukusebenzisana phakathi kwama-photon nama-athomu kungabangela izinhlobo ezintathu zenqubo yokuguquka...Funda kabanzi -
