SLD (Super Luminescent Diode) L8414-04 PRELIMINARY DATA Infrared Emitter with High Radiant Flux Density and Low Coherency ■FEATURES ●High radiant flux density ●Low coherency ■APPLICATIONS ●Optical fiber gyroscopes ●Optical communication ●Optical measurement systems The super luminescent diode (SLD) is an infrared emitter that has the advantages of both the laser diode and the LED; high radiant flux density and low coherency. The SLD was developed as a device that compensates for the disadvantages of laser diodes such as their coherent noise and is therefore ideal for applications where a higher S/N ratio is essential, for example in light-applied measurements and optical communications. A photodiode chip has also been mounted within the same package for monitoring the SLD output. ■ABSOLUTE MAXIMUM RATINGS (Tc=25℃) Parameter Forward Current Radiant flux (Light output) SLD Reverse Voltage PD Reverse Voltage Operating Temperature Storage Temperature Symbol IF φe VR1 VR2 Topr Tstg Value 170 5 1.5 20 -10 to +70 -20 to +80 Unit mA mW V V ℃ ℃ ■ELECTRICAL AND OPTICAL CHARACTERISTICS (Tc=25℃, φe=3mW) Parameter Peak Emission Wavelength Spectral Radiation Half Bandwidth Forward Voltage Forward Current Beam Spread Angle : Parallel : Vertical Monitor PD Current Cut-off Frequency Coherent Length Symbol λp Δλ VF IF θ// θ⊥ Im fc Lc Min. 810 10 1.8 15 25 80 Typ. 830 15 2.0 100 20 35 160 90 50 Max. 850 25 2.2 120 25 45 260 Unit nm nm V mA degree degree μA MHz μm Information furnished by HAMAMATSU is believed to be reliable.
