Measurement Instrumentation

Optical Bandpass WDM FiltersAOT has a well equipped facility for performing feasibility and design verification testing which includes spectrometers, lamp and laser sources and detectors, and high speed electronic instrumentation. AOT also has well-established relationships and experience with facilities offering specialized services and equipment when required.

Software Design Tools

Many problems in optics can be solved with pencil and paper, and while this approach should not be underestimated it is often not enough. On the other hand the availability of sophisticated software tools is also not enough on its own, and it is essential to have the background to choose the correct tool, and to apply it correctly.

ASAP® - Non-Sequential Ray Tracing

MicroRaman SpectroscopyFor applications requiring ray-tracing, for example imaging, illumination or spectroscopic systems we use ASAP®, a fully non-sequential ray-tracing environment from Breault Research Organization. This package is renowned for its flexibility in modeling optical systems including the effects of surface and volume scattering, absorption, fluorescence, ghost image analysis, and much more. It can incorporate the mechanical as well as the optical design, which can show up unintended consequences due to nearby mechanical components or mounting of the optical elements.

GLAD® - Coherent Beam Propagation

When the light involved in an optical system is coherent, or is being focused or manipulated on a wavelength scale, ray tracing is simply not adequate to model the system. Examples include coupling of laser diodes to single mode optical fibers, waveguide models, and micro-optic design. Fully coherent beam propagation is accomplished using GLAD® (General Laser and Amplifier Design) software from Applied Optics Research. This is a very mature and highly capable diffraction propagation package which can handle a wide range of problems, from highly aberrated free space propagation to waveguides.

Mathematica® - Mathematical System Modeling

Microoptic Surface AberrationsSophisticated mathematical analysis is performed with Mathematica® from Wolfram Research. For example, models of noise propagation in communications links and optical amplifier rate equation solutions have been implemented. Simpler models are often created with common spreadsheet programs so they can be readily transferred to the customer for continuing in-house development.

Mechanical and Electronic Design

Through associated organizations AOT can also provide mechanical design using SolidWorks® for 3-D modeling. Electronic design using OrCAD® and other tools is available to provide complete services from PCB design to volume manufacture.
