Coursework for final assessment.
Question: After reading about this review on the development of photonic based biosensors, please write a report covering the following questions;
• What are the key differences between the different biosensors presented in the paper?
• Does any element of the systems require to be built as a coherent photonic system?
• Please be specific on what element in the paper correspond to, or would require a, coherent photonic systems.
• Are there some subsystems used that were seen during the lectures?
• Considering the simple Mach Zehnder senser shown in Fig 1a, derive a sensor sensitivity in terms of minimum refractive index change that can be measured. You might have to make some assumption on the laser source used and the detection system used.
• Please state any assumption you make to assess those parameters.
• The report should not be more than 5000 words and/or 10 pages including figures.

Structure of the
report (15% of total)
|
The report has no structure and does not flow
logically
|
The report has
the premise of a structure, but the flow is not
logical.
|
There is some logic in the
structure. But some gaps are still present
|
The structure is sound and flows logically. It is not complete (Small element missing in discussions
and details)
|
The structure is sound and flows logically. The
level of details is excellent with a high level of
analysis.
|
The structure is at a standard
that could be published in a peer-reviewed journal
|
|
Technical details of
the photonic systems (50% of total)
|
None of the
photonic systems elements for the systems have
been described in the report.
|
Only one of the photonic systems for the systems have been well
presented.
|
Half of the
photonic system elements for the systems have
been well presented.
|
Most of the
photonic system elements have been presented in detail.
|
All the photonic system elements for the systems have been
presented.
|
The level of details is very
high and at a standard
expected for
peer review.
|
|
Derivation on the
systems comparison (35%) of total
|
No derivation to estimate the
sensitivity of the sensor is
presented.
|
The start of the derivation is
presented.
|
A derivation
based on the
lecture notes is presented. It still needs to be
linked to the
actual systems.
|
The derivation is fully linked to the actual systems
and lead to a
conclusion. Some mistakes are
remaining.
|
Full derivation
done and related to the system.
Detailed
conclusion and clear assumption on the system
stated.
|
The conclusions on resolution are advanced.
Discussion are
added on system improvement.
