Analytical expressions for the throughput of a direct space-to-time encoder are used to determine possible output distortions and limitations. The interplay of relevant design parameters is analyzed to avoid such distortions and optimize the performance of the encoder. It is proved that the different propagation angles of the beams in the system produce drastic variations in the coupling coefficient to an optical fiber. It is also shown that it is possible to solve this problem when the throughput of the system is reduced. (C) 2001 Optical Society of America.
