ground. Therefore, an influence of the fluctuation on the
semiconductor diode 1 can be reduced.
Independent claims 5 and 33 are reproduced as fol-
lows:
5. An optical semiconductor device comprising:
a semiconductor laser diode;
a power supply including a bias current source for
biasing said semiconductor laser diode;
an optical modulator for modulating the light output
from said semiconductor laser diode in response to an applied
modulation signal, said semiconductor laser diode and said
optical modulator installed in a package;
a resistor connected in series between an electrode
of said semiconductor laser diode and said bias current source
for inputting bias current to said semiconductor laser diode
to generate light, said resistor being installed in said
package;
common connection means connected to one electrode
of said semiconductor laser diode and to one electrode of said
optical modulator;
at least one of impedance means and signal reflec-
tion means connected to said common connection means; and
ground means connected to at least one of said
impedance means and said signal reflection means.
33. An optical module comprising:
a semiconductor laser diode;
