摘要： Disclosed is a method for maintaining wavelength-locking of a Fabry-Perot laser regardless of a change of external temperature even though a temperature controller is not used, and a wavelength division multiplexing (WDM) light source using the method, as an economical light source used in a WDM optical communication field. The WDM light source comprises a Fabry-Perot laser for injecting spectrum-spliced incoherent light to amplify and output only an oscillation mode matching with a wavelength of the injected light, and a bias controlling unit for adjusting a bias current supplied to the Fabry-Perot laser to a value adjacent to a threshold current of the Fabry-Perot laser, whose threshold current is changed according to a temperature and a relationship between the injected light changed depending to a temperature and a wavelength of the oscillation mode. Therefore, the bias current having a value adjacent to the threshold current of the Fabry-Perot laser is supplied to the Fabry-Perot laser, so that the Fabry-Perot laser can maintain an excellent transmission characteristic regardless of a change of temperature even though a temperature controller is not used.

摘要： An economical wavelength-division-multiplexed passive optical network (WDM-PON) system is realized by directly modulating a wavelength-seeded light source to transmit upstream or downstream data, without using an expensive external modulator. A multiplexed signal having the same wavelength as the waveguide grating is generated and used to control the temperature of the waveguide grating and adjust the wavelength of a wavelength-division-multiplexed signal routed to a transfer link. The wavelength selectivity and stabilization of each light source are not required. Since upstream and downstream signals can be multiplexed and demultiplexed concurrently by each waveguide grating located in the central office and the remote node, it is possible to reduce the number of waveguide gratings used in a WDM optical network. In addition, upstream and downstream signals can be transmitted concurrently using a single-strand transfer optical fiber, thereby realizing an economical and efficient WDM-PON.
摘要翻译：通过直接调制波长种子光源来传输上游或下游数据，实现了经济的波分复用无源光网络（WDM-PON）系统，而不需要昂贵的外部调制器。产生具有与波导光栅相同波长的多路复用信号，并用于控制波导光栅的温度并调节路由到传输链路的波分复用信号的波长。不需要每个光源的波长选择性和稳定性。由于可以通过位于中心局和远程节点中的每个波导光栅同时复用和解复用上游和下行信号，所以可以减少在WDM光网络中使用的波导光栅的数量。此外，可以使用单股传输光纤同时传输上行和下行信号，从而实现经济高效的WDM-PON。
