    • PURPOSE: An external cavity tunable laser module is provided to be able to minutely tune the wavelength of each channel by tuning the wavelength of channels with a specific wavelength gap, and to supply a wide tunable wavelength domain with low power. CONSTITUTION: An external cavity tunable laser module comprises a mirror surface (110), a transmission type liquid crystal filter (120), and a light source chip (140). The mirror surface is formed on a substrate and reflects the laser coming from outside. The transmission type liquid crystal filter is formed on the rear end of the mirror surface, and selects and tunes the laser wavelength reflected by the mirror surface. The light source chip is formed on the rear end of the transmission type liquid crystal filter, reflects the laser passing through the transmission type liquid crystal filter at a specific wavelength gap to form plural channels, and tunes the wavelength of each channel.

    • In a tunable laser device a plurality of basically identical lasers are arranged adjacent to each other in a line or row on a common substrate. The lasers can be DFB-type and they have different emission wavelengths, obtained from e.g. different pitches of gratings which define the wavelengths of the respective lasers. The lasers can be activated to emit light independently of each other by supplying electrical current to contacts located on the top sides of the lasers. When a laser is activated, the other lasers are biased, so that lasers located at one of side of the active laser will be transparent to the emitted light, which can then travel from the lasers through an electrooptic modulator, and the lasers located at the other side will absorb the light. By controlling the temperature the wavelength of emitted light can be finely adjusted. Such a laser device has a compact structure, is fairly insensitive to variations of the used drive currents and can in simple way be adjusted to different operating conditions and be compensated for aging effects.
    • 在可调谐激光器件中,多个基本上相同的激光器在共同的衬底上以行或行的方式彼此相邻布置。 激光器可以是DFB型的,并且它们具有不同的发射波长,例如从例如 定义各激光器波长的不同光栅间距。 通过向位于激光器顶侧的触点提供电流,可以激活激光器以彼此独立地发光。 当激光器被激活时,其他激光器被偏置,使得位于激活激光器一侧的激光器对于所发射的光是透明的,然后激光器可以通过电光调制器从激光器传播,并且激光器位于 对方会吸收光线。 通过控制温度可以精确调整发射光的波长。 这样的激光装置具有紧凑的结构,对所使用的驱动电流的变化相当不敏感,并且可以以简单的方式调整到不同的操作条件并且可以补偿老化效应。
