摘要： Unidirectionality of lasers is enhanced by forming one or more etched gaps (78, 80) in the laser cavity. The gaps may be provided in any segment of a laser, such as any leg of a ring laser, or in one leg (62) of a V-shaped laser (60). A Brewster angle facet at the distal end of a photonic device coupled to the laser reduces back-reflection into the laser cavity. A distributed Bragg reflector is used at the output of a laser to enhance the side-mode suppression ratio of the laser.
摘要翻译：通过在激光腔中形成一个或多个蚀刻间隙（78,80）来增强激光器的单向性。可以在激光器的任何部分（例如环形激光器的任何腿部）中或在V形激光器（60）的一个腿部（62）中提供间隙。耦合到激光器的光子器件的远端处的布鲁斯特角小面减少反射到激光腔。在激光器的输出处使用分布式布拉格反射器来增强激光器的侧模抑制比。

摘要： Three-dimensional structures of arbitrary shape are fabricated on the surface of a substrate (10) through a series of processing steps wherein a monolithic structure is fabricated in successive layers. A first layer (14) of photoresist material is spun onto a substrate (10) surface (18) and is exposed (26) in a desired pattern corresponding to the shape of a final structure, at a corresponding cross-sectional level in the structure. The layer is not developed after exposure; instead, a second layer (30) of photoresist material is deposited and is also exposed (32) in a desired pattern. Subsequent layers (40,52,64) spun onto the top surface of prior layers (14,30) and exposed (44,54,66), and upon completion of the succession of layers each defining corresponding levels of the desired structure, the layers are all developed at the same time leaving the three-dimensional structure (22).

摘要： A controllable, unidirectional ring laser having a reduced length includes at least one curved waveguide section (42), at least one partially transmitting facet (62), and a mechanism for producing unidirectional propagation of light within the waveguide cavity .The mechanism includes an external reflector (102), which may be either planar or curved, in the path of emitted light from a waveguide facet. In another embodiment, the reflector is replaced by a source of light (220) directed at the emitting facet of the waveguide. Another embodiment includes the use of an asymmetric element in the cavity .If desired, two unidirectional devices can be used selectively to produce a reversible waveguide.

摘要： 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.
