| Abstract: | ![]()
A novel Y-branch based monolithic transceiver with a superluminescent diode and a waveguide photodiode (Y-SDL-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 patterns, based on the beam propagation method (BPM). The amplified spontaneous emission of the device is up to 10mW at 120mA with no threshold and saturation. Spectral characteristics of about 30nm width and less than 1dB modulation are achieved using the built-in anti-lasing ability ofY-branch. The beam divergence angles in horizontal and vertical directions are optimized to as small as 12°× 8°, resulting in good fibre coupling. |
