Claim:
1. A wavelength swept optical source, comprising: a micro optical bench; a source for generating broadband light; a first tunable Fabry Perot filter, installed on the bench, for spectrally filtering the broadband light from the broadband source to generate a tunable signal, wherein a full width half maximum bandwidth of the first Fabry-Perot tunable filter is less than 20 GHz; an amplifier, installed on the bench, for amplifying the tunable signal; at least one filter-amplifier lens, installed on the bench, for coupling the tunable signal from the first tunable Fabry Perot filter into the amplifier; a second tunable Fabry Perot filter, installed on the bench, for spectrally filtering the amplified tunable signal from the amplifier; and at least one amplifier-filter lens, installed on the bench, for coupling the tunable signal from the amplifier into the second tunable Fabry Perot filter; wherein the amplifier is located on the bench optically between the first tunable Fabry-Perot filter and the second tunable Fabry-Perot filter.
