Optical pulse addition device |
摘要 |
<p>SC light is generated from the input signal 2, of an OTDM signal light 1 with wavelength lambda s1 and an input signal 2 with wavelength lambda s2 using an optical fiber and the like, and the wavelength of the SC light is converted into wavelength lambda s1 using a BPF with center wavelength lambda s1 (a specific-timing optical pulse with wavelength lambda s1 is extracted from the SC light). After the addition timing of the wavelength-converted light is adjusted by a delayer ( tau ), both this wavelength-converted light and signal light 1 are inputted to an optical add circuit and are added. <IMAGE></p> |
