摘要	Wavelength reference apparatus for use in calibrating a tunable Fabry-Perot filter or a tunable VCSEL, whereby the device may be tuned to a precise, known wavelength, the wavelength reference apparatus comprising an LED, where the LED is chosen so as to have an emission profile which varies with wavelength; an etalon, where the etalon is chosen so as to have a transmission profile which comprises a comb of transmission peaks, with each transmission peak occurring at a precise, known wavelength; and a detector for detecting the light emitted by the LED and passing through the etalon; whereby when a tunable Fabry-Perot filter or tunable VCSEL is positioned between the etalon and the detector, and the device is swept through its tuning range by varying the tuning voltage applied to the device, the known transmission wavelengths established by the LED and the etalon can be correlated to counterpart tuning voltages of the device, whereby to calibrate the device.
其他摘要	用于校准可调法布里 - 珀罗滤波器或可调谐VCSEL的波长参考设备，其中该设备可被调谐到精确的已知波长，该波长参考设备包括LED，其中LED被选择为具有发射随波长变化的轮廓;标准具，其中选择标准具以便具有包括透射峰梳的透射分布，每个透射峰出现在精确的已知波长;检测器，用于检测LED发出的光并通过标准具;因此，当可调谐法布里 - 珀罗滤波器或可调谐VCSEL位于标准具和检测器之间，并且通过改变施加到器件的调谐电压来扫描器件的调谐范围时，由LED和标准具建立的已知传输波长可以与器件的对应调谐电压相关联，从而校准器件。
主权项	A wavelength reference apparatus for use in calibrating a device comprising a tunable Fabry-Perot filter or a tunable VCSEL, the wavelength reference apparatus being configured to tune the device to a precise, known wavelength, the wavelength reference apparatus comprising; an LED, the LED having an emission profile which varies with wavelength; an etalon, where the etalon is chosen so as to have a transmission profile which comprises a comb of transmission peaks, with each transmission peak occurring at a precise, known wavelength; a detector for detecting the light emitted by said LED and passing through said etalon; and the device being positioned between said etalon and said detector, and the device being swept through its tuning range by varying the tuning voltage applied to the device, the known transmission wavelengths established by said LED and said etalon are correlated to counterpart tuning voltages of the device so as to calibrate the device.
