What does an IC Solutions PICS specialist do?
An IC Solutions PICS specialist designs and simulates photonic integrated circuits to prepare optical devices for fabrication and system-level evaluation. This role bridges the gap between theoretical optical physics and practical semiconductor manufacturing by creating precise digital models of light behavior within microchips. The specialist uses electromagnetic solvers to predict how photons interact with specific materials and structures before any physical prototype exists. They generate the exact data files foundries require to print these complex optical pathways onto silicon wafers.
- Builds and runs electromagnetic simulations for individual device components and larger optical structures using tools like RSoft Photonic Device Tools. The specialist defines scan parameters and optimization goals to refine how light propagates through waveguides, modulators, and detectors. This process produces detailed characteristics of device performance under various conditions without needing physical testing equipment.
- Exports simulation results as Process Design Kit (PDK) compatible data and S-matrix representations for downstream circuit integration. These exports allow other engineers to include the photonic component in larger system models without re-running heavy electromagnetic calculations. The specialist ensures the exported data accurately reflects the simulated behavior so system-level predictions remain reliable.
- Generates and verifies GDS layout outputs that meet strict foundry submission requirements for physical manufacturing. This task involves translating the optimized optical design into geometric shapes that lithography machines can interpret and print on silicon. The specialist checks these layouts against design rules to prevent fabrication errors that would ruin the costly manufacturing run.
- Connects device simulations to circuit and system analysis tools like ADS Photonic Designer to evaluate overall chip behavior. This step confirms that individual components work together correctly when signals pass through the entire photonic network. The specialist adjusts design parameters based on these system-level insights to improve signal integrity and reduce loss across the full chip.
How to hire an IC Solutions PICS specialist on Upwork
Step 1: Post a job
Define your photonic integrated circuit requirements clearly to attract qualified candidates. Use the Job Post Generator powered by Uma™, Upwork's Mindful AI to draft a precise description in seconds. Describe your needs for PIC simulation or layout design, and Uma constructs a tailored post. You can write a new post, update a saved draft, or reuse an existing post.
- Specify required electromagnetic solvers such as RSoft FullWAVE or BeamPROP for device modeling.
- List deliverables like GDS layout outputs or PDK-compatible data exports for foundry submission.
- State if Python API scripting is needed to automate structure creation or parameter scans.
Step 2: Evaluate candidates
Look for portfolios that demonstrate verified photonic device simulations and system-level analysis. Uma can run instant video interviews and build shortlists with side-by-side comparisons to speed up this process. Focus on candidates who show concrete results from optical design workflows.
- Review examples of exported S-matrix data used for downstream optical circuit simulation.
- Check for equivalent refractive index (Neff) calculations derived from complex waveguide structures.
- Verify experience with ADS Photonic Designer for composing multi-component photonic circuits.
Step 3: Interview your top choices
Discuss specific technical challenges related to your photonic integration goals. Schedule and conduct interviews within Upwork Messages, which generates an immediate transcript and summary after each session. This keeps your hiring process organized and searchable.
- Ask how they optimize simulation parameters to balance accuracy with computational runtime.
- Request details on their method for validating simulation results against measured device performance.
- Discuss their approach to preparing fabrication-ready layouts that meet foundry design rules.
Step 4: Agree on scope and begin work
Set clear milestones for simulation runs, data exports, and layout verification. Use Upwork Messages and the contract workroom for all communication and project management tasks. Identity verification, payment protection, hourly tracking, and project funds add security to every engagement.
- Define milestones for completing electromagnetic simulations and exporting PDK inputs.
- Agree on file formats for deliverables, such as GDSII for layouts or CSV for Neff data.
- Establish a review cycle for checking simulation convergence and layout integrity before submission.
