半导体放大器SOA

 Innolume 半导体放大器SOA     半导体光放大器（Semiconductor Optical Amplifiers,SOA）是采用半导体增益介质的一种光放大器。半导体光放大器具有结构简单、体积小，制作工艺成熟、成本低、寿命长、功耗小等特点。SOA通常用于通信系统中的全光中继放大器、接收机前置放大器等。 量青光电为您提供Innolume 波长范围780nm到1330nm的波段各种波长、功率、尾纤的半导体光放大器，您可以根据自己的实际需求选购合适的产品。 Semiconductor optical amplifiers (booster optical amplifiers) are amplifiers which use a semiconductor to provide the gain medium. They have a similar structure to Fabry–Perot laser diodes but with anti-reflection design elements at the end faces. Recent designs include anti-reflective coatings and tilted waveguide and window regions which can reduce end face reflection to less than 0.001%. Since this creates a loss of power from the cavity which is greater than the gain, it prevents the amplifier from acting as a laser. Optical coherence tomography (OCT) is a low coherence interferometry technique that generates backscattering profiles of tissue. OCT has been very successful in ophthalmology in diagnosing eye diseases and it is widely applied in other areas such as dentistry, endoscopy and dermatology. Light sources are a crucial component in the design of OCT systems as they decide the resolution along the optical axis as well the depth penetration of infrared light in tissue. Swept-source lasers (SSL) are the light source of choice for Fourier domain optical coherence tomography (FDOCT). The gain medium in SSL is most often a semiconductor optical amplifier (SOA). Their main advantage is fast carrier dynamics which ensures fast buildup of lasing within the cavity. Furthermore, a wider tuning range can be achieved by employing several SOAs in parallel.   Typical parameters of fiber-coupled SOAs Part number Gain mean wavelength Gain bandwith FWHM1 Small signal gain1 Saturation output power2 Noise figure Gain maximum wavelength Gain spectrum dip ASE power ASE ripples RMS3 PER Operating current nm nm dB dBm dB nm dB mW dB dB mA SOA-1000-100-YY-30dB 1000 100 33 17 6 955, 1030 1 25 0.02 20 600 SOA-1020-110-YY-27dB 1020 110 27 15 7.5 970, 1040 4 15 0.02 20 450 SOA-1030-20-YY-40dB 1030 20 40 18 8 1030 - 70 0.03 20 400 SOA-1060-20-YY-40dB 1060 22 40 18 8 1065 - 60 0.02 20 400 SOA-1060-90-YY-30dB 1060 90 30 18 5 1060 - 7 0.02 20 400 SOA-1080-20-YY-40dB 1080 27 38 17 7 1085 - 40 0.02 20 400 SOA-1130-20-YY-35dB 1125 25 35 15 10 1125 - 30 0.03 20 600 SOA-1140-90-YY-24dB 1140 90 24 17 4.5 1110, 1170 5 1.4 0.01 20 400 SOA-1190-90-YY-20dB 1190 90 20 15 6.5 1160, 1225 5 0.7 0.02 20 300 SOA-1250-110-YY-27dB 1250 110 27 15 7.5 1210 , 1280 6 5 0.05 20 900 SOA-1290-40-YY-25dB 1285 45 24 12 7.5 1290 - 1 0.02 20 400 1 - @ - 25dBm input signal, gain maximum 2 - @ - 3dB, gain maximum 3 - @ ASE maximum, RMS in 1 nm range, 10pm resolution 780nm到1330nm范围内，可指定波长     联系人： Michael 李     手机：173-1762-8715  (欢迎来电) 工作邮箱:   michael@qoptronics.com     咨询QQ:  3191209539 (欢迎咨询) 公司固话：021-64778883
