Abstract

An optical module includes a driver that generates an electric signal and an optical modulator that has a notch in which at least a portion of the driver is accommodated and performs optical modulation using an electric signal generated by the driver. The optical module also includes a first connector electrically connected to the driver in the notch of the optical modulator. The optical module further includes a second connector provided on a surface of the notch of the optical modulator, the surface being opposed to the first connector. The second connector is electrically connected to the optical modulator. Furthermore, the optical module includes a coaxial pin that is connected to the first connector and the second connector and transmits the electric signal generated by the driver to the optical modulator.

First claim

What is claimed is:

1. An optical module comprising:
a driver that generates an electric signal;
an optical modulator that includes a notch in which at least a portion of the driver is accommodated, and performs optical modulation using the electric signal generated by the driver;
a first connector that is electrically connected to the driver in the notch of the optical modulator;
a second connector that is provided on a surface of the notch of the optical modulator and is electrically connected to the optical modulator, the surface being opposed to the first connector; and
a coaxial pin that is connected to the first connector and the second connector and transmits the electric signal generated by the driver to the optical modulator.

2. The optical module according to claim 1 , wherein
the first connector is fixed to a substrate with an insertion port thereof facing a thickness direction of the substrate in the notch of the optical modulator, and is electrically connected to the driver via a first electrode pattern on the substrate,
the second connector is provided on the surface of the notch of the optical modulator, the surface being opposed to the first connector, with an insertion port thereof facing the thickness direction of the substrate and is electrically connected to the optical modulator, and
the coaxial pin is connected to the first connector and the second connector by being inserted into the insertion port of the first connector and the insertion port of the second connector.

3. The optical module according to claim 2 , wherein the first connector is fixed to the substrate via a base member on which a plurality of the first connectors are arranged in an array.

4. The optical module according to claim 1 , wherein
the first connector is fixed to the driver with an insertion port thereof facing a direction crossing a thickness direction of a substrate in the notch of the optical modulator, and is electrically connected to the driver,
the second connector is provided on the surface of the notch of the optical modulator, the surface being opposed to the first connector, with an insertion port thereof facing the direction crossing the thickness direction of the substrate and is electrically connected to the optical modulator, and
the coaxial pin is connected to the first connector and the second connector by being inserted into the insertion port of the first connector and the insertion port of the second connector.

5. The optical module according to claim 2 , wherein
the optical modulator further includes another notch different from the notch and a terminal that is for inputting a signal different from the electric signal and projects to the another notch, and
the terminal is electrically connected to a second electrode pattern on the substrate in the another notch of the optical modulator.

6. The optical module according to claim 4 , wherein
the optical modulator further includes another notch different from the notch and a terminal that is for inputting a signal different from the electric signal and projects to the another notch, and
the terminal is electrically connected to a second electrode pattern on the substrate in the another notch of the optical modulator.

7. The optical module according to claim 1 , wherein the first connector and the coaxial pin are integrally formed with each other.

8. The optical module according to claim 1 , wherein the second connector and the coaxial pin are integrally formed with each other.
