Question

Q5) A 64 x 64 port transmissive star coupler has 1.6 mW of optical power launched into a single input port. If the device exhibits an excess loss of 3.90 dB, determine the total loss through the device and the average optical power level that would be expected at each output port.

Step 1

Excess loss is given as 3.90 dB, which means that the device loses 3.90 dB of power compared to the ideal case. To convert dB to a linear scale, we use the formula: Loss (linear scale) = 10^(excess loss in dB/10) So, the total loss through the device is: Total Show more…
