A novel Y-branch based monolithic transceiver with a superluminescent diode and a waveguide photodiode(YSDL-PD)is designed and fabricated by the method of bundle integrated waveguide (BIG) as the scheme for monolithic integration and angled Y-branch as the passive bi-directional waveguide.The simulations of BIG and Y-branches show low losses and improved far-field pattes,based on the beam propagation method(BPM).The amplified spontaneous emission of the device is up to 10 m W at 120 m A with no threshold and saturation.Spectral characteristics of about 30 nm width and less than 1 dB modulation are achieved using the built-in antilasing ability of Y-branch.The beam divergence angles in horizontal and vertical directions are optimized to as small as 12°×8°,resulting in good fibre coupling.
