MY LEGAL POST photo parametric amplifier

hi guys
since a month ago till today the admins delete my threads i don't know why but i am sure without any reason but i think the only unique reason due to my technical questions! however today i will use all my rights as a mimber in edaboard website i want to refer to the rules which accept me to ask my question. maybe the person who delete and blocked my accounts forgot the website rules.

MY TECHNICAL QUESTION is
can any one of you explain to me how the signal amplify due to the photo parametric amplifier. i mean the signal will amplify before the photo diode ( at the receiver ) or it will amplify after the photo diode ? ( because i am trying to model this system)

---------- Post added at 16:57 ---------- Previous post was at 16:55 ----------

is my question quite enough to made you confused? no one able to contribute to catch the answer ?

I don't know about your earlier posts but I don't understand your current question.

tnx about ur replay
my question was> i want know how the signal amplify using parametric amplifier in optical fiber systems

The basic idea is presented here: Optical parametric amplifier - Wikipedia, the free encyclopedia

hi FvM. i want know the signal will amplify before the photo diode ( at the receiver ) or it will amplify after the photo diode ?

Optical amplifier implies that in- and output signal are optical. It has to be placed before a receiver.

hi FvM
tnx for your daily support and tnx for your helpful. can you be specific even a bit more.?

There are plenty of references around - you just need to search:

Encyclopedia of Laser Physics and Technology - optical parametric amplifiers, OPA, non-degenerate, phase-sensitive amplification

Encyclopedia of Laser Physics and Technology - parametric amplification, phase sensitive, amplifier, phase insensitive, signal, idler, gain, phase mismatch, fiber

tnx toooo much my soledad for your helpful, could you plz help me to get a simulation for a parametric amplifier using any software. plz i am waiting your present.

Sorry, I don't have any simulation software for optical amplifiers - only electronics ones.

Keith.

tnx for your encourage. my G O D bless u and ur family
