Abstract

THE THEORETICAL ANALYSES OF PHASE I STUDY INDICATE THAT THE TUNING RANGE OF A 1.3 MICROMETER LASER DIODE COMBINED WITH ELECTRO-OPTIC MODULATORS (EOM) CAN WELL EXCEED 450 A. FOR PHASE II R&D, E-TEK PLANS TO DEVELOP THE PACKAGED MULTIWAVELENGTH NARROW-BAND SOURCES (MNS) TO DEMONSTRATE THE PRACTICALITY, VIABILITY, RELIABILITY, PRODUCIBILITY OF MNS WHICH CAN MEET REAL SYSTEM NEEDS. TO INTEGRATE WITH COMMERCIALLY AVAILABLE LASER CHIPS, THE PRECISION EOMS WILL BE FABRICATED AND CHARACTERIZED AT E-TEK FOR CONSTRUCTING AN ELECTRONICALLY TUNABLE MNS. PRIOR TO THE FINAL MNS DEVELOPED, TWO TUNABLE MNS CONFIGURATIONS WILL BE DESIGNED, FABRICATED, AND TESTED. COMPARING EXPERIMENTAL RESULTS WITH THE THEORETICAL PREDICTIONS, INCLUDING TUNABILITY, TUNING SENSITIVITY, TEMPERATURE EFFECTS, MODULATION FREQUENCY, POST TUNING DRIFT, AND OPTICAL POWER OUTPUT/UNIFORMITY, WILL PRACTICALLY LEAD THE FUTURE DESIGNS MEETING EACH INDIVIDUAL SYSTEM REQUIREMENTS. TO SATISFY THE STRINGENT THERMAL/MECHANICAL TOLERANCES, MINIATURE SIZE, PRECISE DIMENSION REQUIREMENTS, AND ENVIRONMENTAL CONDITIONS, E-TEK WILL EXERCISE ITS ACCUMULATED EXPERIENCE WITH MINIATURE XYZ POSITIONERS AND EXTEND THE ACCURACY TO 0.1 TO 0.2 MICROMETERS. IN PHASE II, THE DELICATE METHODS OF ALIGNMENT/INTEGRATION/PACKAGING WILL BE DEVELOPED AND VERIFIED. THE HIGH PERFORMANCE CONTROL/BIAS/STABILITY ELECTRONICS ARE ALSO CONSTRUCTED TO MEET THE MNS SPECIFICATIONS.
