I have a transmitting fiber and a receiving fiber. Now the transmitting fiber core diameter is 50 micrometer and I want to know how many receiving fibers should be used so all light from transmitted fiber is received properly.
As suggested by some friends beam follows the Gaussian distribution. So I tried searching and got these link http://www.mellesgriot.com/products/optics/gb_2_2.htm
where I assumed that w(z) should be radius of my receiving fiber as I was thinking using 2 of receiving fiber of 200 micrometer so I thought maybe I should use 200 micrometer as radius or w(z) value. The wavelength I used was from 400nm to 900nm and got z that is separation distance as 20 mm to 38 mm. I don't know if it is right. I assumed starting beam radius which is w0 as 25 mm as core diameter of transmitting tube is 50 mm
Now I have a power output of 1w so I need to know what should be intensity which my recieveing fibers will recieve. I have got the formula for intensity here http://www.mellesgriot.com/products/optics/gb_2_1.htm
but it has a parameter r which if i have understand correectly is same as w. so I am confused.
Can anyone please help
