摘要：一种基于表面光栅的DFB激光器。激光器为脊形波导结构，自下而上包含：衬底（1）、下波导盖层（3）、有源层（4）、上波导盖层（5）；在脊形波导表面上刻蚀有布拉格光栅（11）；脊区采用高折射率材料，使光栅（11）具有大的耦合系数；脊形波导上面不做电极，上电极（13）位于脊形波导两侧；在脊形波导与两侧上电极（13）之间刻蚀有沟槽；激光器的下波导盖层（3）中含有一个或多个电流限制区（12），或者是在上波导盖层（5）中制作一个掩埋隧道结来限制电流。激光器不需要材料的二次外延生长，制作工艺简便，因而降低了激光器的制作成本，提高了激光器的可靠性。此外激光器可以获得大的耦合系数，因而在激光器腔长很短的情况下能获得低阈值以及高速直调的激光器性能。

摘要： An example system includes a grating coupled laser, a laser optical interposer (LOI), an optical isolator, and a light redirector. The grating coupled laser includes a laser cavity and a transmit grating optically coupled to the laser cavity. The transmit grating is configured to diffract light emitted by the laser cavity out of the grating coupled laser. The LOI includes an LOI waveguide with an input end and an output end. The optical isolator is positioned between the surface coupled edge emitting laser and the LOI. The light redirector is positioned to redirect the light, after the light passes through the optical isolator, into the LOI waveguide of the LOI.

摘要： A transversely-coupled distributed feedback laser diode (100), which can be processed without overgrowth, is disclosed. The laser is made from an epitaxial heterostructure including a core layer (140) located between two cladding layers (130, 150), a cap layer (170), and at least one Al-rich layer (160). The lateral waveguide is formed by selective oxidation of the Al-rich layer. A surface corrugated grating (171, 172) is formed above the waveguide. The heteroepitaxial structure is designed so that the core layer is placed in close proximity to the top of the laser structure to provide a required overlap between the light and the grating. In order to avoid inadmissible optical losses, there is no metallization above the waveguide. Instead, the metal contacts (190) are offset at some distance, so that the current has to spread in the cap layer before vertical injection into the core layer.
摘要翻译：公开了一种横向耦合的分布反馈激光二极管（100），可以在不产生过度增长的情况下进行处理。该激光由外延异质结构制成，其包括位于两个覆层（130,150），覆盖层（170）和至少一个富铝层（160）之间的芯层（140）。侧向波导通过富Al层的选择性氧化形成。表面波纹光栅（171,172）形成在波导上方。异质外延结构被设计成使得芯层被放置成紧邻激光结构的顶部以提供光和光栅之间所需的重叠。为了避免不可接受的光损耗，在波导上方没有金属化。相反，金属触点（190）在一定距离处偏移，使得电流必须在垂直注入芯层之前在盖层中扩展。

摘要： A saturable absorber (SA) based on a high-contrast grating (HCG) having a buried layer of quantum structures for absorption, and which is particularly well suited for use in a mode-locked application. The HCG-SA provides three times the bandwidth compared with traditional DBR structures, while exhibiting a lower saturation fluence due to the field enhancement inside the grating. Varying grating bar width over one or two axis provides lensing effects on the optical output, while chirping of the period and duty cycle changes optical phase relationships. Novel VCSEL embodiments with external or internal cavities are described using the HCG-SA.
摘要翻译：基于具有用于吸收的量子结构的掩埋层的高对比度光栅（HCG）的可饱和吸收体（SA），特别适用于锁模应用。与传统的DBR结构相比，HCG-SA提供了三倍的带宽，同时由于光栅内的场增强而呈现较低的饱和能量密度。在一个或两个轴上变化的光栅条宽度对光输出提供透镜效应，而周期和占空比的啁啾会改变光学相位关系。使用HCG-SA描述具有外部或内部空腔的新型VCSEL实施例。

摘要： A semiconductor laser is formed on a semiconductor substrate with an array of laterally spaced laser device elements each including a second order distributed feedback grating bounded by distributed Bragg reflector gratings and a central phase shift in the distributed feedback grating. The device elements in which the distributed feedback grating and the distributed Bragg reflector gratings are formed have a lower effective index than the index of the interelement regions and are spaced so as to form an antiguided array. A twodimensional semiconductor array laser may be formed of four or more of the semiconductor array devices arranged on the substrate to provide long range coherent coupling via traveling waves of light between the device elements.
