Area of Science:

• Optoelectronics
• Solid-state lasers
• Optical communication

Background:

• High-bit-rate optical communication requires efficient and stable laser transmitters.
• Solid-state lasers offer potential advantages in terms of stability and wavelength flexibility.

Purpose of the Study:

• To fabricate a pure single-mode solid-state laser transmitter for high-bit-rate applications.
• To characterize the performance of the developed laser transmitter in terms of output power, wavelength, and bandwidth.

Main Methods:

• Fabrication of a laser transmitter using a Gallium Aluminum Arsenide (GaAlAs) laser-pumped Lithium Neodymium Tetraphosphate (LiNdP(4)O(12)) laser oscillator.
• Integration of a Yttrium Iron Garnet (YIG) isolator and a Lithium Niobate (LiNbO(3)) traveling-wave directional-coupler waveguide modulator.
• Coupling the signal to an output single-mode fiber for measurement.

Main Results:

• Achieved a signal peak power of 0.17 mW coupled to an output single-mode fiber.
• Operated at a wavelength of 1.317 micrometers.
• Measured a half-wavelength voltage of 6.0 V and a 3-dB bandwidth of 2.8 GHz.

Conclusions:

• A pure single-mode high-bit-rate solid-state laser transmitter was successfully fabricated.
• The developed transmitter demonstrates promising performance for optical communication systems.
• The results indicate the potential of LiNdP(4)O(12) based solid-state lasers for high-speed applications.
