Unit Information

The unit will provide theoretical and practical training to lay the foundations of knowledge required to design, simulate and tapeout a photonic integrated circuit (PIC). General cleanroom nanofabrication techniques will be covered in lectures, whilst maintaining a general focus on reasons they are essential for the development of PICs. A series of computational solvers will be used to simulate the design parameters required to implement successful PIC design. A lithographic design tool (CAD) will be exploited to design lithographic masks that are required to conform to strict foundry design rules and are then sent to a foundry for fabrication. Practical cleanroom sessions comprising spin-coating of photoresist, contact lithography, etching and microscopy tools, will be followed with optical laboratory characterisation of PICs designed by the previous cohort. This will provide students with extensive hands-on training.

Aim: To provide an overview of nano-engineering capabilities and challenges. To enable students to map a PIC fabrication flow given a device idea. Understand system limitations, what can and cannot be made.

Your learning on this unit

Upon completion of this unit, students should:

  • Have a thorough appreciation of the broad usage of PICs.
  • Appreciate general cleanroom fabrication techniques, in particular those typically used in a PIC fabrication workflow.
  • Have a full appreciation of the PIC design, simulation, and fabrication workflow.
  • Experience a range of electromagnetic computational simulation solver to model the flow of light onto and through a PIC.
  • Use these solvers to model waveguide light confinement, light coupling to a PIC, the splitting and filtering of light on a PIC, and how these components are combined to produce photonic systems.
  • Experience of a range of nano fabrication and characterisation techniques
  • Appreciate the workflow for the PIC cleanroom fabrication process
  • Gain a familiarity with designing lithography masks for foundry tapeout.

How you will learn

Teaching will be delivered through a combination of synchronous and asynchronous sessions, including lectures, practical activities supported by drop-in sessions, problem sheets and self-directed tasks.

How you will be assessed

5000-word report on the mini project, weighted at 100%. This assessment will address all of the intended learning outcomes.

For reassessment, a revised version of the originally submitted report will be submitted.

Resources

If this unit has a Resource List, you will normally find a link to it in the Blackboard area for the unit. Sometimes there will be a separate link for each weekly topic.

If you are unable to access a list through Blackboard, you can also find it via the Resource Lists homepage. Search for the list by the unit name or code (e.g. PHYSM0055).

How much time the unit requires
Each credit equates to 10 hours of total student input. For example a 20 credit unit will take you 200 hours of study to complete. Your total learning time is made up of contact time, directed learning tasks, independent learning and assessment activity.

See the University Workload statement relating to this unit for more information.

Assessment
The assessment methods listed in this unit specification are designed to enable students to demonstrate the named learning outcomes (LOs). Where a disability prevents a student from undertaking a specific method of assessment, schools will make reasonable adjustments to support a student to demonstrate the LO by an alternative method or with additional resources.

The Board of Examiners will consider all cases where students have failed or not completed the assessments required for credit. The Board considers each student's outcomes across all the units which contribute to each year's programme of study. For appropriate assessments, if you have self-certificated your absence, you will normally be required to complete it the next time it runs (for assessments at the end of TB1 and TB2 this is usually in the next re-assessment period).
The Board of Examiners will take into account any exceptional circumstances and operates within the Regulations and Code of Practice for Taught Programmes.
