摘要： The present application relates to a method of fabricating planar circuits using a photo lithographic mask set, to the photo lithographic mask set, and to a planar circuit fabricated with the photo lithographic mask set. The instant invention involves separating a photo lithographic mask into two parts, namely, a master mask and one or more slave masks. The master mask and the one or more slave masks form a photo lithographic mask set that is used iteratively to fabricate the planar circuits. In particular, the master mask is used as a template to provide the general layout for the planar circuit, while each slave mask is varied to tune and/or tailor the planar circuit. Since only a small portion of the planar circuit is redesigned and/or rewritten as a new mask (i.e., the slave mask), the instant invention provides a simple and cost effective method for optimizing planar circuits. Furthermore, since most mask errors will originate from the master mask, the instant invention provides an efficient method of correcting errors on planar circuits using the one or more slave masks.
摘要翻译：本申请涉及使用光刻掩模组，光刻掩模组以及用光刻掩模组制造的平面电路制造平面电路的方法。本发明涉及将光刻掩模分为两部分，即主掩模和一个或多个从属掩模。主掩模和一个或多个从属掩模形成用于迭代地制造平面电路的光刻掩模组。特别地，主掩模用作模板以提供用于平面电路的总体布局，而每个从屏蔽被改变以调谐和/或定制平面电路。由于只有一小部分平面电路被重新设计和/或重写为新的掩模（即，从属掩模），本发明提供了一种用于优化平面电路的简单且成本有效的方法。此外，由于大多数掩模错误将源自主掩模，本发明提供了使用一个或多个从属掩码来校正平面电路上的误差的有效方法。

摘要： Planar waveguide devices are described which function as elements of a soliton transmission communications system operating at a selected central wavelength. These devices have at least one optical channel waveguide whose core has a refractive index and dielectric constant with a dependence on the optical signal intensity which can balance a negative dispersion in the waveguide at dimensions compatible with monomode transmission of the selected central wavelength. It is a property of such a waveguide that if the input is an optical soliton, the output will also be a soliton. Such circuits are useful at the input and output of a soliton transmitting fiber as part of a high bit-rate (broadband) communications system.

摘要： The invention relates to a variable optical attenuator constructed as a Mach Zehnder planar lightwave circuit, particularly including a channel waveguide support structure for heat isolation and stress relief to reduce polarization dependent loss (PDL) and power consumption in the device. Power reduction trenches comprise longitudinal segments having small stress relief pillars of cladding material left in between them in the etching process. The waveguides of the MZI are supported by a main pillar structure and integral stress relief pillars which remain after removal of the trenches. The waveguide is surrounded by air on three sides for improved heat isolation. The performance of the present invention shows substantial improvement in PDL and extinction ratio over the prior art continuous trench design, and also, to a smaller degree, over the case where power reduction trenches are not used at all. Segmented trenches appear to allow for the lowest stress on the two waveguide arms of all the cases including no trench and trenched devices.

摘要： A planar waveguide device is described which can function as either a switching or power dividing element of a soliton transmission communication system operating at a selected central wavelength. The device has one input and two outputs and consists of two optical channel waveguides, in a coupler-like configuration, each of whose cores has a refractive index and dielectric constant with a dependence on the optical signal intensity which can balance a negative dispersion in the waveguide at dimensions compatible with monomode transmission of the selected central wavelength. It is a property of such waveguides that if the input to one channel waveguide is a temporal optical soliton, the output will also be a temporal soliton, and the output waveguide, or waveguides, from which it exits the device as well as the power of the switched or power divided signal at each output will be dependent upon the input soliton peak power. Such switching and power dividing circuits are useful at the input and output of soliton transmitting fibers as part of a high bit-rate (broadband) communication system.

摘要： A planar waveguide Mach-Zehnder interferometer (MZ) has improved performance as a variable optical attenuator as well as a thermo-optic switch (TOS) with reduced polarization dependent loss (PDL) in high attenuation states. The PDL was reduced by correcting for the increased birefringence that occurs on heating one waveguide arm by making the two waveguides inherently asymmetric, such that when one of the waveguides is heated, the differential birefringence of the two arms becomes zero. This asymmetry can be realized simply by changing the width of one of the waveguides. The modified device allows for very small PDL in the high attenuation state of a VOA and for theoretically perfect contrast in a TOS in the off state, with only a small penalty in PDL of the on state.
