    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蚀刻小面激光腔,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,两个腔体结构大大提高了所制造的芯片的产量。

    Abstract: A ring cavity laser (20) has at least two facets (32,34) and a mechanism is provided to produce unidirectional propagation and light emission at a first wavelength. A source of laser light (60) at a second wavelength is injected into the cavity to reverse the direction of propagation and to produce emission at the second wavelength.
