摘要： The present invention discloses a low-noise optical signal transmitter with a low-noise multi-wavelength light source, a broadcast signal transmitter using a low-noise multi-wavelength light source, and an optical communication network and an optical network with the same. The present invention uses an LMLS (Low-noise Multi-wavelength Light Source) which oscillates at multiple wavelengths with low enough noise at each wavelength. The output light of this LMLS has no increase in noise at each wavelength even when passing through a wavelength division multiplexer/demultiplexer such as a variable optical filter or arrayed waveguide grating. A wavelength division multiplexed-passive optical network which simultaneously enables ultra-high speed optical signal transmission and multi-cast signal transmission can be implemented using the LMLS. Furthermore, an optical amplifier implemented using a gain medium for the LMLS has no cross-coupling and can obtain a gain within a wide band.

摘要： The present invention discloses a wavelength division multiplexed-passive optical network (WDM-PON) using a multi-mode laser diode having a multi-contact. The WDM-PON according to the present invention uses a range with a low noise within a mode partition noise spectrum as a data transmission band, instead of inserting an incoherent light source from outside, in order to reduce a mode partition noise, and uses a transmission format having high-spectrum efficiency so as to accomplish a large capacity of a network at a low cost and improves transmission efficiency further. In addition, in the WDM-PON according to the present invention, it is possible to embody a WDM-PON at a low cost by compensating an increase of a mode partition noise or an optical power loss, due to the discrepancy between a transmission wavelength of an arrayed waveguide grating (AWG) being used as a wavelength- division multiplexer/de-multiplexer and a center wavelength of the multi-mode laser diode having the multi-contact depending on a temperature change, through controlling injected electric current which runs in the multi-contact of the multi-mode laser diode.
