A 64 x 32 liquid-crystal-on-silicon (LCOS) microdisplay with a frame buffer pixel architecture is described. The advantage of frame buffer pixel circuits is an increase in brightness and image contrast ratio. The increase in brightness is attributed to maximizing the overall image viewing time, allowing an image to be displayed at full contrast while the… (More)
In this paper, we propose the power detection (PD)-based TDM-PON architecture, which is implemented for a hardware-based decentralized DBA (dynamic bandwidth allocation) among ONUs, without OLT's intervention to service. The proposed approach is characterized by a simple, fast and cost-effective operation on TDM-PON.
3D-IC mixed-signal systems introduce vertical noise coupling which is a new noise coupling path by near-field coupling between logic ICs and RF/analog ICs. To guarantee the performance of the system, we should be aware of the amount of the vertical noise coupling during the system design stage. This paper reports the frequency-domain and time-domain… (More)
This paper investigates a hybrid wavelength division multiplexing (WDM) multiple access protocol combining the advantages of preallocation and reservation-based schemes using a subcarrier multiplexing (SCM) technique for passive double star optical networks. We include a node-grouping scheme in the proposed protocol to increase channel utilization and to… (More)
