摘要 | PURPOSE:To obtain an optically multiplex light source of a structure, wherein a plurality of optical frequency PLL parts, which control the wavelength of input light corresponding to the wavelength of input light and are mutually connected in vertical connection, and a reference light source, which applies a light of a constant wavelength to the input of the first-stage optical frequency PLL part, are provided and the output light each have the prescribed frequency interval to the input light in the second-stage PLL part and the PLL part that follows that. CONSTITUTION:In an optical frequency PLL part 2, the output wavelength is locked a wavelength to correspond to the wavelength of a reference wavelength light source 1 and light is incided in an optical frequency multiplication part 23. A secondary high-frequency output light, which is inputted using a 4-layer slab waveguide consisting of air-TiO2-ZnS-glass, is obtained, an optical heterodyne detection part 21 outputs a frequency difference between the output light and the output light of the light source 1 and the difference is controlled to an equal frequency f01=1/2Xfs in a variable wavelength light source part 22. In a PLL part 3, a reference offset frequency f0S is applied to an optical heterodyne detection part 31 and the output of a variable wavelength light source 32 becomes f02=(1/2)fS+f0S and in a PLL part 4, the output of a variable wavelength light source 42 becomes f03=(1/2)fS+2f0S. Photo output having the interval f0S can be obtained correctly from the PLL part of each stage. |
其他摘要 | 目的:获得一种结构的光学多路复用光源,其中控制输入光波长的多个光学频率PLL部分与输入光的波长相互垂直连接,以及参考光源,提供将恒定波长的光应用于第一级光学频率PLL部分的输入,并且输出光每个具有规定的频率间隔到第二级PLL部分和随后的PLL部分中的输入光。那。组成:在光频PLL部分2中,输出波长被锁定一个波长,以对应于参考波长光源1的波长,并且光被固定在光频率中乘法部分23.获得使用由空气-TiO2-ZnS-玻璃组成的4层平板波导输入的次级高频输出光,光学外差检测部分21输出输出光和之间的频率差。在可变波长光源部分22中,光源1的输出光和差被控制到相等的频率f01 = 1 / 2Xfs。在PLL部分3中,参考偏移频率f0S被施加到光外差检测部分。如图31所示,可变波长光源32的输出变为f02 =(1/2)fS + f0S,在PLL部分4中,可变波长光源42的输出变为f03 =(1/2)fS + 2f0S。可以从PLL部分正确地获得具有间隔f0S的光输出每个阶段。 |
