教学工作

讲授内容：

1. Basic optical devices and systems:

①Basic principles, characteristics, parameters：optical sources， optical receivers，optical modulators，optical couplers, and etc.

②Traditional optical systems： 谐振式光学陀螺（Resonant Optic Gyro，ROG）， wavelength division multiplexed （WDM）fiber optic link

2. Test and measurements techniques

①Optical power measurement. Power is one of the fundamental properties of a lightwave signal. The photodetector is the most common device for measuring power.

②Optical spectrum analysis. The measurement of the wavelength of light is another fundamental lightwave property.

③Common measurement technique: using a diffraction grating as an optical filter.

④ Accurate wavelength measurements (1550 ± 0.001 nm, for example) can be made by using a Michelson interferometer

⑤ Very high resolution: Heterodyne and homodyne spectrum analysis

⑥ Insertion loss measurements. The measurement of the loss of multi-port optical devices is covered.Methods to resolve loss versus wavelength.

⑦ Polarization. The polarization of lightwave signal is another fundamental property. The fiber medium tends to change the polarization state of a signal dramatically as light propagates down the length.

⑧ Return loss measurements. The reflectivity of optical components is an important measurement. Systems are often intolerant of reflections. Total return-loss measurements and high-resolution spatially resolved measurement of reflectivity.

⑨ Opticalreflectometry.

光时域反射技计 （Optical Time Domain Reflectometry，OTDR): One of the most important measurement areas in fiber optic communications. When a fiber is broken in a system, OTDRs are used to locate the break
