SUMMARY OR ABSTRACT
Text of Note
The slotted tunable laser described here has many advantages over other state of the art semiconductor tunable laser diodes, however there are also some disadvantages with the slotted tunable laser design. The key advantages of this laser are: a. no re-growth step is required during manufacturing b. no output facet necessary for operation so cleaving is not required c. highly compatible with integration d. insensitive to feed-back, therefore may not require optical isolator e. high switching speed of the order of 1 ns f. potentially very narrow line-width (of the order of MHz, unconfirmed) The major advantages of the SFP tunable laser relate to the simpler manufacturing process enabled by the lack of any re-growth step being required. In addition no cleaving is required and this provides its compatibility with integration. This combination should provide an opportunity to obtain high yields with complex integrated devices, such as, a tunable laser, modulator and SOA.
