I need help designing a nanoscale device. I am trying to find a way to produce 16 light frequencies (or more) using a single quantum dot. There may be some way to do this using a filtering mechanism or something, but I will let you come up with the solution. The total device must be under 10 nanometers. Let's work together to create something great.
The 16 frequencies should be able to be generated dynamically. So the user of the device can switch between each frequency. The frequencies should not be output all at once.
The device should be able to save it's state when it is powered off. So if it is electrically powered, when it is turned off, it should save the light frequency it is on. Therefore the next time it is powered up it will emit the saved light frequency.
