    Abstract: A laser (22) and detector (24) integrated on corresponding epitaxial layers of a single chip (20) cooperate with on-chip and/or external optics (62) to couple light of a first wavelength emitted by the laser to a single external device such as an optical fiber (60) and to simultaneously couple light of a different wavelength received from the external device to the detector to provide bidirectional photonic operation. Multiple lasers and detectors may be integrated on the chip to provide multiple bidirectional channels.

    Abstract: A surface emitting photonic device including a substrate; and a waveguide structure on the substrate. The waveguide structure includes an active region along its longitudinal axis and the active region is for generating light. The waveguide structure also has a trench formed therein transverse to the active region and defining a first wall forming an angled facet at one end of the active region, the first wall having a normal that is at a non-parallel angle relative to the longitudinal axis of the waveguide structure. The trench also defines a second wall located opposite the first wall.

    Abstract: A semiconductor chip has at least two DFB etched facet laser cavities with one set of facets with AR coatings and a second set of etched facets with HR coatings that have a different relative position with respect to the gratings. This creates a difference in the phase between each of the etched facets and the gratings which changes the operational characteristics of the two laser cavities such that at least one of the lasers provides acceptable performance. As a result, the two cavity arrangement greatly improves the yield of the fabricated chips.

    Abstract translation: 半导体芯片具有至少两个具有AR涂层的DFB刻蚀小面激光腔，其具有一组具有AR涂层的刻面，以及具有HR涂层的第二组蚀刻刻面，其具有相对于光栅的不同相对位置。 这产生了每个蚀刻面和光栅之间的相位的差异，其改变了两个激光腔的操作特性，使得至少一个激光器提供可接受的性能。 结果，两个腔体布置大大地提高了所制造的芯片的产量。

    Abstract: Semiconductor photonic device surfaces are covered with a dielectric or a metal protective layer. The protective layer covers the entire device, including regions near facets at active regions, to prevent bare or unprotected semiconductor regions, thereby to form a very high reliability etched facet photonic device.
