The MPW Base Passive PIC consists of one silicon and two silicon nitride waveguides. A trench is available to remove most of cladding oxide over the first nitride waveguide. On the base passive PIC build build, silicon waveguide propagation loss target is 0.75 dB/cm while the silicon nitride waveguide propagation loss target is 0.5 dB/cm. Lower loss waveguides are available with our other offerings. The Base Passive PIC is supported by component libraries from Analog Photonics (APSUNY), Spark Photonics, the Research Foundation for SUNY (RFS) and Dream Photonics. Customization Available - Adjust ridge depth - Adjust waveguide thicknesses - Adjust vertical spacing between waveguides - Trench to the Si waveguide - Fully expose Si or SiN waveguide in the bottom of a trench While MPWs typically follow a standard process flow that designers cannot modify, AIM Photonics has developed a “bite-size” custom offering where designers can make minor changes to the process flow for an additional fee. This is not a full custom run, and the modification must be something the fab team can execute without development work. The exact specifications and complexity of the design may affect which run it will ultimately ride on, and in most cases, this can vary between one and two months. Please contact us well in advance of the design due date to ensure the fab team understands your request and can properly quote the work.
