We demonstrate a monolithically integrated coherent receiver PIC on an InP substrate with a 120° optical hybrid and 40GHz pin-photodetectors. Moreover, the performance of the device for colorless detection of 28Gbaud 16-QAM signals in the C- and L-band is investigated.
It is presented a single-feed dual-frequency triangular Planar Inverted-F Antenna with U-shaped sleeves in this paper. A shorting-wall and a V-shaped slot are introduced to enhance the bandwidths in lower operating and higher operating frequency respectively. For return loss (S11) ≤-10dB, a relative bandwidth of more than 25% (2.1GHz-2.7GHz) at lower operating frequency and of more than 19.3% (4.9GHz-5...
In this paper, we propose an accurate full 3D EM behavioral model of PD chips for the first time. The model, which is meshed at 130 GHz, runs for about 17 minutes on an Intel Core2 Duo CPU@3 GHz PC with 3.5 GB of RAM. The impact of various parameters in wire- bonding transitions for transmission characteristic is summarized in the Table I. When numbers of bonding wires are placed separately all through...
