1.
Consult table on page 6 for the particular wavelength ranges that are available.
2. Typical values at 25 °C and 0.6 NA collection optics.
3. Features common to these products include:
a. Duty factor of 100%.
b. Temperature coefficient of wavelength is approximately 0.27 to 0.3 nm/°C.
c. Temperature coefficient of threshold current can be modeled as:
ITH2 = ITH1 exp [(T2 – T1)/T0]
where T0 is a device constant of about 160 °K.
d.Temperature coefficient of operating current is approximately 1% per °C.
4. Modulation bandwidth of CW diode lasers is approximately 1 GHz though the effective rep rates are dependent on drive signals and use conditions.
5. Forward voltage is typically:
Vf = 1.5 V + Iop x Rs.
6. The 2380 series near field consists of two active segments separated by an isolation space to produce specified aperture.
