I attended the SHM meet and thought it may be good to pass along some observations from a technical perspective of the packaged modulator and lab tour.
Packaged Modulator:
Reported speed: 50 Gbps
- May support up to 100-200 Gbps data rates using PAM4 encoding
Low Vpi: Approximately 3-4V.
- This spec is the distance between peaks and nulls of the optical power out of the modulator. In practice, the bias voltage of the modulator is set so the optical power out of the modulator is at the midpoint with no modulating signal output applied (called quadrature).
- Low Vpi is important to the datacenters because it reduces the voltage required to operate/bias the modulator. A lower bias voltage operating point results in proportionally lower power requirements.
- The Vpi of LWLG P2IC modulators is approximately half that of traditional LiNB M-Z modulators.
Stable Modulator Bias Point:
- Very stable bias point observed
- Traditional LiNB M-Z modulators have fairly high electrode capacitance. This results in a drift of the bias voltage used to place the modulator in quadrature (ie., the optimum point to bias the modulator).
- This causes distortion which affects the spectral purity of the datastream, causes interchannel interference, and - in general - degrades the performance of the modulator.
- The LWLG P2IC modulator appeared to have a very stable (repeatable) bias point...significantly better than what I have observed in LiNb modulators.
General Lab Observations
Clean and well-organized
Capable of manufacturing small quantities of modulators:
- Large-scale production of modulators will still need to be outsourced
Ability to manufacture integrated multiplexed Laser/Modulator devices
- There is a huge market application for multiplexed laser/modulator devices where four or more InPh lasers and modulators are on the same substrate with the respective modulator outputs routed to an on-chip multiplexer (WDM, etc.).
- LWLG has the ability to manufacture prototypes of these devices in-house as they get the performance of the modulators optimized.
