Hi EveryOne. . .
I am a student currently pursuing my Masters of Engineering in MEMs, and I came
up with a project in optical MEMS, whereby the intensity of light at the output
is controlled by the amount of light incidents on the input. The proposed
scheme is that:-
[OPERATION PRINCIPLE]
A coherent light at the input strikes a 'micro-photodetector' and the voltage
generated by the 'micro-photodetector' is used to actuate a pair of electrodes
with one of them fixed and the other one connected to a movable mirror. The
position of the mirror plays a role in determining whether the light
interference occurs at the output is constructive or destructive, thereby
realising the 'On'-'OFF' state. Because the switching state depends on the
superposition of light, it can either be analog or digital in nature.
(i hope the above description of the principles without a diagram is
sufficiently clear)
[QUESTIONS]
My concern is that, "IS THE RESEARCH DIRECTION OF THE PROJECT SOUND?"
It is because:-
1. present state of the art is [OO - Optical-optical] configuration and
the proposed switching device proposed above is [OEO -
Optical-Electrical-Optical]
2. As a light switch, it has only 1X1 channel, whereas the current state
of the art is something greater than 10X10 channel?
3. And if the eventual application is proposed as a MEMS optical
transistor, would the mechanical switching speed demerit its functions as a
MEMS transistor?
Just for information, I am using only CoventorWare for simulations and the
project involves little or no fabrication at all.
Can anyone please advice me whether or not the direction of this project is
sound/ worth pursuing? Because I would not want to invest additional time and
afford before realising that the direction needs changing.
[MODIFICATION]
If the project direction needs changing, can anyone suggest me a more
meaningful direction to pursue?
Thank you very much in advance. Kind helps are gratefully cherished.
Best regards,
