mitsubishi laser diodes ml9xx19 series 2.5gbps ingaasp dfb laser diodes type name ml925b19f description ml9xx19 series are uncooled dfb (distributed feedback) laser diodes for 2.5gbps transmission emitting light beam with wavelength of 1470~1610nm. l/4 shifted grating structure is employed to obtain excellent smsr performance under 2.5gbps modulation. furthermore, ml9xx19 can operate in the wide temperature range from 0 o c to 70 o c without any temperature control. they are well suited for light source in long distance digital transmission application of coarse wdm. features n l/4 phase shifted grating structure n wide temp erature range operation (0 o c to 70 o c ) n high side - mode - suppression - ratio(typical 45db) n high resonance frequency(typical 11ghz) application n 2.5gbps long - reach transmission n coarse wdm application absolute maximum ratings symbol parameter conditions ratings unit po light output power cw 6 mw if laser forward current - 200 ma vrl las er reverse voltage - 2 v ird pd forward current - 2 ma vrd pd reverse voltage - 20 o c tc operation temperature - 0 to +70 o c tstg storage temperature - - 40 to +100 o c electrical/optical characteristics(tc=25 o c) symbol parameter test conditions min. typ. max. unit cw --- 15 30 ith threshold current cw,tc=70 o c -- - 35 50 ma cw, po=5mw,tc=70 o c --- 40 60 iop operation current cw, po=5mw --- 70 100 ma vop operating voltage cw, po=5mw --- 1.1 1.8 v l p peak wavelength cw, po=5mw <* , **> nm h slope efficiency cw, po=5mw 0.15 0.20 --- mw/ma q// beam divergence angle (parallel) <1> cw, po=5mw --- 25 40 deg. q^ beam divergence angle ( perpendicular ) <1> cw, po=5mw --- 30 47 deg. smsr side mod e suppression ratio cw, po=5mw, tc=0 ~ 70 o c 35 45 --- db tr,tf rise and fall time (10% - 90%) 2.48832gbps, ibias=ith short lead - pin --- 100 150 psec fr resonance frequency 2.48832gbps,ibias=ith,ipp=40ma --- 11 --- db im monitor current (pd) cw, po=5mw, v rd=1v, 0.1 --- 2.0 ma id dark current (pd) vrd=5v --- --- 1.0 m a ct capacitance (pd) vrd=5v, f=1mhz --- 10 20 pf note : <1> exclude back facet reflection from a monitor pd mitsubishi electric j u n . 2002 preliminary notice: this is not a final s pecification . some parametric limits are subject to change.
