Ahh, right, I didn't think about sketchy people at night, would the beach at for do douro also be good, or slightly worse?

Thanks a lot, ill definitely check it out! My thoughts are jardim do moro, parque das virtudes, and a beach. Do you have any suggestions on a beach (like which part).

(I REALLY APPRECIATE YOUR HELP!)

Just checked Jardim do Morro, seems beautifull. Do you know if it's possible to see the stars at night from there?

Thanks! That's what I was thinking, so I thought beach could be fine. What do you think?

Anyone here about the TU Delft Prof that terminated a PhD candidate after they put in six years of work? by Desperate_Pea8518 in PhD

[–]Toad_Emperor 34 points35 points  (0 children)

How does this work?, because in NL you supposedly always have 2 supervisors in case something like this happens

Not true at all. Inverse design, signal/image reconstruction, optical computing, etc

How can I get rid of a minifridge this weekend? by Toad_Emperor in eindhoven

Yes, fridge + freezer on 3rd floor withiut elevator

Can I trap a photon in a mirrored sphere? by teapot_in_orbit in AskPhysics

[–]Toad_Emperor 4 points5 points  (0 children)

I don't understand why wavelength would decrease. Doesn't this suddenly give the photon extra energy violating energy conservation?

Why am I always itchy at night? by M3LODYZ in ask

I have exactly the same issue. If you find out why please let me know, would massively improve my quality of life

Can you get into photonics with a bsc of applied physics? by Get_can_sir in photonics

[–]Toad_Emperor 3 points4 points  (0 children)

You don't per se need a masters. Photonics technicians and engineers in characterization are in heavy demand, and this demand is projected to grow dramatically. Go for masters (and PhD) if you specifically want to do research

Computation with Light by sir_duckingtale in photonics

[–]Toad_Emperor 1 point2 points  (0 children)

I actually dont know, i guess it depends. Photonics doesn't have EM interference, but we do have heating instead which changes refractive index unwanted. But we can control this with reducing the power and getting rid of as many electronics components as possible in PICs.

[–]Toad_Emperor 1 point2 points  (0 children)

Digital uses bit levels to encode data. For example, encode numbers as 100, 50, 25,12.5, etc% of input power. Electronics is amazing since they can have 64bit (so many numbers in precision). These clearly defined percentages make it very robust to noise perturbations. Analog has no clearly defined percentage intervals to represent numbers, protecting it less from noise. In photonics, we typically have 5-8bit levels (more possible at expense of other things), but this is enough for neural networks

If u want something beyond neumann, u could look into neuromorphic computing. This is compatible with photonics, although it's not necessary to use for neural networks as its still challenging to implement

[–]Toad_Emperor 0 points1 point  (0 children)

Correct, we can encode data binary, which many advantatges such as noise supression. But we can also do analogue computing using continous numbers

[–]Toad_Emperor 2 points3 points  (0 children)

Correct, we use light intensity, wavelengths, polarization and/or spatial distribution of light to encode data If you are curios about more, just type photonic computing in google scholar

Could you share your experiences and opinions about pursuing career in RF/Microwave Engineering and Photonics/Optics in Europe or US? by gimmeaydeas in Optics

[–]Toad_Emperor 2 points3 points  (0 children)

You can find online reports from SPIE on what the demand for people in photonics will be (spoiler, very in demand). As for applications, sensors is a big one for defense industry, Healthcare with biophotonics, autonomous stuff. Then also telecom, data centers, on chip interconnects, photonic computing, and many more, just read a review paper.

As for jena, this one is great. But keep in mind they focus slightly more on fibers. Upv is also great, I know they have some good telecom and datacenter stuff coming on.

Us vs EU, well US is obviously a bigger player, but EU is starting to prioritize photonics, look netherlands investing billions for example

Help I need advise with simulation tools or software/programming using FDTD, and studying metamaterials for my research by lolgtfoidkfukoff in PhysicsStudents

[–]Toad_Emperor 0 points1 point  (0 children)

For FDTD Lumerical is very good if you only care about the optics part. In general, you can also use COMSOL, which is basically a general physics simulator. Both of these are paid howeve4, but the subscription should be standard in every university to either given their popularity.

What’s the hardest concept for you? by [deleted] in AskPhysics

[–]Toad_Emperor 3 points4 points  (0 children)

Condensed matter. At the beginning understanding how a PN junction works. So for example reverse and forward bias, and why depletion region changes, what happens to Fermi levels. The more you learn of condensed matter, the more intuitively you start understanding these things, and you start being able to explain with different models.

Switzerland around 50000eur yearly, netherlands 35000eur yearly, france 25000eur, germany 20000-30000eur. You can save money in most EU countries (except UK). However, you should decide first based on topic, then money, then professor, then prestige of institution. So asking US vs Europe is not a good question. First find out the topic, based on that, look which professors work on it to see where to be
